Dear Ms. Collins:

I refer to the Staff's comment letter dated June 26, 2007 to Compuware
Corporation and my telephone conversation with Ms. Christine Davis regarding the
due date for responding to your comments. The Company has requested an extension
of the due date in order to have sufficient time for compilation and review
internally and by the Company's advisers of the responses to the Staff's
comments. The Company confirms that it intends to submit its responses to the
Staff's comments by July 20, 2007.

The Company appreciates your cooperation in extending the deadline for their
response.

Please feel free to call me at (313) 227-7372 with any questions or if we can be
of any assistance.

Very truly yours,



/s/ Laura L. Fournier
