                   GROWTH IN REVENUE, EARNINGS AND CASH BUILDS
                    FOUNDATION FOR EXPANSION INTO NEW MARKETS

BEDFORD, MASS., NOVEMBER 4, 2004 - MRO Software, Inc. (Nasdaq: MROI), the
leading provider of strategic asset management solutions, today announced
revenues of $49.9 million for the Company's fourth quarter and $185.7 million
for the fiscal year ended September 30, 2004.

Total revenues for the fourth quarter were $49.9 million compared with $46.0
million for the fourth quarter last year an increase of 8 percent. Revenues for
the fiscal year ended September 30, 2004 were $185.7 million, compared with
$176.9 million for the prior year, an increase of 5 percent.

On a GAAP basis, the Company reported net income for the fourth quarter of $4.1
million or $0.16 per diluted share, compared with net income of $2.6 million or
$0.11 per diluted share for the same quarter last year, an increase in EPS of 38
percent. On a GAAP basis for the fiscal year ended September 30, 2004, the
Company reported net income of $10.3 million or $0.40 per diluted share compared

During the fourth quarter, the Company sold 269 software licenses into a broad
range of industries. Customers that purchased MRO Software solutions during the
quarter included: ABB, AMTRAK, Ames Labs, City of Austin, China National
Offshore Oil Company (CNOOC), Department of Energy, EDS, General Mills, Guinness

SpA, Kaiser Aluminum and Chemical, Kuwait Oil Tanker Co., Land Securities

The balance sheet as of September 30, 2004 contained $108.4 million in cash and
marketable securities and no long-term debt. This compares with $94.6 million in
cash and marketable securities as of September 30, 2003, and represents a 15
percent increase year-over-year. For the fourth quarter, deferred revenue was
$30.3 million, and days sales outstanding (DSO) were 66.

"The Company delivered on its earnings and growth projections for the year,"
said Chip Drapeau, president and CEO, MRO Software. "Our industry solutions
continued to be important revenue drivers for the fourth quarter and the fiscal
year. The last two years of solid financial performance has provided the
foundation to launch our next generation asset and service management solution,
Maximo Enterprise Suite. Product development is complete, we are in the final
stages of QA, and early customer feedback has been positive. We are confident
with our plan to launch Maximo Enterprise Suite early in calendar year 2005."

"The Company is very sound financially," said Peter Rice, executive vice
president and CFO, MRO Software. "We had a strong fourth quarter, and for the
year we met our revenue growth targets, earnings improved by more than 50
percent on a pro forma basis, and 100 percent on a GAAP basis, and we
significantly improved our cash position."

For fiscal year 2005, the Company expects software revenues to grow in the range
of 10 to 20 percent above fiscal 2004 results. It is anticipated that operating
margins will continue to increase. As a result, the Company expects earnings to
increase in the range of 15 to 25 percent over fiscal 2004 results on a pro
forma basis. Consistent with prior performance, and due to the timing of the
release of the Maximo Enterprise Suite, the Company expects most of the
anticipated revenue growth to occur in the second half of the fiscal year.
Specifically, in the first quarter of fiscal 2005 revenues are expected to be in
the range of $45 to $47 million, GAAP earnings to be in the range of $0.08 to
$0.10 per share, and pro forma earnings to be in the range of $0.10 to $0.12 per
share.

Expected results on a pro forma basis are adjusted for the amortization of
acquired technology and other intangibles and their related tax effects (see
Schedule A).

NOTE:

     In this press release, the Company announced its earnings per share (EPS)
     on a GAAP and pro forma basis. Pro forma net income for fiscal year 2004
     and 2003 is adjusted to exclude the amortization of acquired technology and
     other intangibles and their related tax effects.

     Management believes that such pro forma EPS is useful to investors, first
     because it is important for investors to receive information in a form that
     is consistent with the Company's past practice, and second because the
     Company's amortization of acquired technology and other intangibles is
     substantially fixed, and is relatively large in comparison with the
     absolute value of the Company's operating income. The Company believes that
     by focusing on the impact of expenses that are to a greater extent subject
     to control by the Company's management, pro forma EPS provides investors
     with a more direct perspective on the performance of the Company and its
     management.
