Welcome, Shareholder:

In this report, you'll learn about how your investment in Morgan Stanley Quality
Municipal Investment Trust performed during the semiannual period. We will
provide an overview of the market conditions, and discuss some of the factors
that affected performance during the reporting period. In addition, this report
includes the Trust's financial statements and a list of Trust investments.

Market forecasts provided in this report may not necessarily come to pass. There
is no assurance that the Trust will achieve its investment objective. The Trust
is subject to market risk, which is the possibility that market values of
securities owned by the Trust will decline and, therefore, the value of the
Trust's shares may be less than what you paid for them. Accordingly, you can
lose money investing in this Trust.


FUND REPORT

For the six-month period ended April 30, 2004

MARKET CONDITIONS


The U.S. economy continued to show improvement over the six-month period under
review. On the positive side, gross domestic product growth topped 4 percent in
both quarters. While strength in output has historically led to higher interest
rates, yields remained stubbornly low across the curve. These yields reflected
low levels of observed inflation in the economy and gradual improvement in
employment. The Federal Open Market Committee maintained its accommodative
monetary policy.

Surprising job growth in March, combined with escalating oil prices, led
investors to anticipate that the Fed would raise interest rates sooner rather
than later. Yet at its April meeting the Federal Reserve did not change its
short-term lending rate but did signal a prospective shift in policy. As a
result, bond yields spiked across sectors and maturities.

The supply of new municipal bonds in calendar 2003 reached record levels as
municipalities took advantage of historically low interest rates. Many cities
and states reduced expenditures by refinancing existing debt at lower yields. In
other cases, municipalities attempted to meet budget needs by issuing additional
debt. Then in the first months of 2004 bond sales began to slow.

Low interest rates also had an impact on the demand for municipal bonds. Retail
and mutual fund activity slowed as holders of municipal bonds saw little reason
to sell bonds purchased at higher yields and reinvest at historically low
yields. However, insurance companies and hedge funds purchased municipal bonds
based on their attractiveness relative to taxable securities. Additionally,
investors stretched for yield by buying lower-rated bonds, causing credit
spreads to tighten.

PERFORMANCE ANALYSIS


The net asset value (NAV) of Morgan Stanley Quality Municipal Investment Trust
(IQT) decreased from $15.36 to $15.05 per share for the six-month period ended
April 30, 2004. Based on this change plus reinvestment of tax-free dividends
totaling $0.45 per share and long-term capital gains of $0.027 per share, the
Trust's total NAV return was 1.21 percent. The Trust's value on the New York
Stock Exchange (NYSE) decreased from $14.22 to $13.28 per share during the same
period. Based on this change plus reinvestment of distributions, the Trust's
total market return was -3.47 percent. On April 30, 2004, IQT's NYSE market
price was at an 11.76 percent discount to its NAV. Past performance is no
guarantee of future results.

Monthly dividends for the second quarter of 2004, declared in March, were
unchanged at $0.075 per share. The dividend reflects the level of the Trust's
undistributed net investment income and projected earnings power. The Trust's
level of undistributed net investment income was $0.113 per share on April 30,
2004, versus $0.137 per share six months earlier.

The Trust's duration(1) was targeted to be shorter than its benchmark index. The
duration, adjusted for leverage, was 12.3 years. Treasury futures were sold to
reduce interest-rate exposure without raising cash in the portfolio. We
maintained an average tax-exempt bond maturity objective of 20 years to take
advantage of the steepness of the municipal yield curve. Revenue bonds in
sectors with reliable income streams from essential services such as municipal
electric, transportation and water and sewer systems were emphasized. The
Trust's net assets, including preferred shares of $345 million, were diversified
across 13 credits in 69 long-term sectors.

As discussed in previous reports, the total income available for distribution to
holders of common shares includes incremental income provided by the Trust's
outstanding Auction Rate Preferred Shares (ARPS). ARPS dividends reflect
prevailing short-term interest rates on maturities ranging from one week to two
years. Incremental income to holders of common shares depends on two factors:
the amount of ARPS outstanding, and the spread between the portfolio's cost
yield and its ARPS auction rate and expenses. The greater the spread and the
higher the amount of ARPS outstanding, the greater the amount of incremental
income available for distribution to holders of common shares. The level of net
investment income available for distribution to holders of common shares varies
with the level of short-term interest rates. ARPS leverage also increases the
price volatility of common shares and has the effect of extending portfolio
duration.

During the six-month period under review, ARPS leverage contributed
approximately $0.09 per share to common-share earnings. The Trust has two ARPS
series totaling $105 million and representing 30 percent of net assets including
preferred shares. The series is currently in two-year auction modes with
maturities ranging from September 2004 to September 2005. The yields ranged from
1.70 to 1.90 percent.

The Trust's procedure for reinvesting all dividends and distributions in common
shares is through purchases in the open market. This method helps support the
market value of the Trust's shares. In addition, we would like to remind you
that the Trustees have approved a procedure whereby the Trust may, when
appropriate, purchase shares in the open market or in privately negotiated
transactions at a price not above market value or net asset value, whichever is
lower at the time of purchase. The Trust may also utilize procedures to reduce
or eliminate the amount of outstanding ARPS, including their purchase in the
open market or in privately negotiated transactions.

- ----------------------------------------------------
1 A measure of the sensitivity of a bond's price to changes in interest rates,
  expressed in years. Each year of duration represents an expected 1 percent
  change in the price of a bond for every 1 percent change in interest rates.
  The longer a bond's duration, the greater the effect of interest-rate
  movements on its price. Typically, Funds with shorter durations perform better
  in rising-rate environments, while Funds with longer durations perform better
  when rates decline.

Morgan Stanley Quality Municipal Investment Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2004 (UNAUDITED)

1. Organization and Accounting Policies

Morgan Stanley Quality Municipal Investment Trust (the "Trust") is registered
under the Investment Company Act of 1940, as amended, as a diversified,
closed-end management investment company. The Trust's investment objective is to
provide current income which is exempt from federal income tax. The Trust was
organized as a Massachusetts business trust on July 2, 1991 and commenced
operations on September 27, 1991.

The following is a summary of significant accounting policies:

A. Valuation of Investments -- (1) portfolio securities are valued by an outside
independent pricing service approved by the Trustees. The pricing service uses
both a computerized grid matrix of tax-exempt securities and evaluations by its
staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the mean between the last reported bid and
asked price. The portfolio securities are thus valued by reference to a
combination of transactions and quotations for the same or other securities
believed to be comparable in quality, coupon, maturity, type of issue, call
provisions, trading characteristics and other features deemed to be relevant.
The Trustees believe that timely and reliable market quotations are generally
not readily available for purposes of valuing tax-exempt securities and that the
valuations supplied by the pricing service are more likely to approximate the
fair value of such securities; (2) futures are valued at the latest sale price
on the commodities exchange on which they trade unless it is determined that
such price does not reflect their market value, in which case they will be
valued at their fair value as determined in good faith under procedures
established by and under the supervision of the Trustees; and (3) short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to maturity
and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.

B. Accounting for Investments -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.

C. Futures Contracts -- A futures contract is an agreement between two parties
to buy and sell financial instruments or contracts based on financial indices at
a set price on a future date. Upon entering into such a contract, the Trust is
required to pledge to the broker cash, U.S. Government securities or other
liquid portfolio securities equal to the minimum initial margin requirements of
the applicable futures exchange. Pursuant to the contract, the Trust agrees to
receive from or pay to the

14


Morgan Stanley Quality Municipal Investment Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2004 (UNAUDITED) continued

broker an amount of cash equal to the daily fluctuation in the value of the
contract. Such receipts or payments known as variation margin are recorded by
the Trust as unrealized gains and losses. Upon closing of the contract, the
Trust realizes a gain or loss equal to the difference between the value of the
contract at the time it was opened and the value at the time it was closed.

D. Federal Income Tax Policy -- It is the Trust's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable and nontaxable
income to its shareholders. Accordingly, no federal income tax provision is
required.

E. Dividends and Distributions to Shareholders -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

F. Use of Estimates -- The preparation of financial statements in accordance
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts and disclosures.
Actual results could differ from those estimates.

2. Investment Management Agreement

Pursuant to an Investment Management Agreement with Morgan Stanley Investment
Advisors Inc. ("the Investment Manager"), the Trust pays the Investment Manager
a management fee, calculated weekly and payable monthly, by applying the annual
rate of 0.35% to the Trust's weekly total net assets.

3. Security Transactions and Transactions with Affiliates

The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the six months ended April 30, 2004 aggregated

Morgan Stanley Trust, an affiliate of the Investment Manager, is the Trust's
transfer agent. At April 30, 2004, the Trust had transfer agent fees and
expenses payable of approximately $12,000.

The Trust has an unfunded noncontributory defined benefit pension plan covering
certain independent Trustees of the Trust who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on factors which include years of service and compensation.
Aggregate pension costs for the year ended April 30, 2004 included in Trustees'
fees and expenses in the Statement of Operations amounted to $3,404. At April

participants and eliminate the future benefits growth due to increases to
compensation after July 31, 2003.

Effective April 1, 2004, the Trust began an unfunded Deferred Compensation Plan
(the "Compensation Plan"), which allows each independent Trustee to defer
payment of all, or a portion, of the fees he receives for serving on the Board
of Trustees. Each eligible Trustee generally may elect to have the deferred
amounts credited with a return equal to the total return on one or more of the
Morgan Stanley funds that are offered as investment options under the
Compensation Plan. Appreciation/depreciation and distributions received from
these investments are recorded with an offsetting increase/decrease in the
deferred compensation obligation and do not affect the net asset value of the
Trust.

4. Preferred Shares of Beneficial Interest

The Trust is authorized to issue up to 1,000,000 non-participating preferred
shares of beneficial interest having a par value of $.01 per share, in one or
more series, with rights as determined by the Trustees, without approval of the
common shareholders. The Trust has issued Series A and Series B Auction Rate
Preferred Shares ("Preferred Shares") which have a liquidation value of $50,000
per share plus the redemption premium, if any, plus accumulated but unpaid
dividends, whether or not declared, thereon to the date of distribution. The
Trust may redeem such shares, in whole or in part, at the original purchase
price of $50,000 per share plus accumulated but unpaid dividends, whether or not
declared, thereon to the date of redemption. Dividends, which are cumulative,
are reset through auction procedures.

Subsequent to April 30, 2004 and up through June 4, 2004 the Trust paid
dividends to Series A and B at rates ranging from 1.70% to 1.90% in the
aggregate amount of $160,419.

The Trust is subject to certain restrictions relating to the preferred shares.
Failure to comply with these restrictions could preclude the Trust from
declaring any distributions to common shareholders or purchasing common shares
and/or could trigger the mandatory redemption of preferred shares at liquidation
value.

On March 30, 2004, the Trust declared the following dividends from net
investment income:

 AMOUNT        RECORD         PAYABLE
PER SHARE       DATE           DATE

$0.075..    June 4, 2004   June 18, 2004
</Table>

7. Expense Offset

The expense offset represents a reduction of the custodian fees for earnings on
cash balances maintained by the Trust.

8. Risks Relating to Certain Financial Instruments

The Trust may invest a portion of its assets in residual interest bonds, which
are inverse floating rate municipal obligations. The prices of these securities
are subject to greater market fluctuations during periods of changing prevailing
interest rates than are comparable fixed rate obligations.

To hedge against adverse interest rate changes, the Trust may invest in
financial futures contracts or municipal bond index futures contracts ("futures
contracts").

                                                                              17


Morgan Stanley Quality Municipal Investment Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2004 (UNAUDITED) continued

These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of Assets and Liabilities. The Trust bears the risk
of an unfavorable change in the value of the underlying securities. Risks may
also arise upon entering into these contracts from the potential inability of
the counterparties to meet the terms of their contracts.

9. Federal Income Tax Status

The amount of dividends and distributions from net investment income and net
realized capital gains are determined in accordance with federal income tax
regulations which may differ from generally accepted accounting principles.
These "book/tax" differences are either considered temporary or permanent in
nature. To the extent these differences are permanent in nature, such amounts
are reclassified within the capital accounts based on their federal tax-basis
treatment; temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for tax purposes are reported as distributions of paid-in-capital.

As of October 31, 2003, the Trust had temporary book/tax differences primarily
attributable to book amortization of discounts on debt securities,
mark-to-market of open futures contracts and dividends payable.
