Compuware

(CPWR)

warned investors Friday that its fiscal first-quarter earnings will fall significantly short of Wall Street estimates, making it the latest in a bevy of technology companies that have issued advanced notice of lower quarterly earnings.

Compuware, seller of software and services that test, maintain, and debug computer software and systems, said its earnings for the quarter ended June 30 are likely to be in a range between 7 and 9 cents a share, roughly half of the 15 cents a share forecast by a consensus of Wall Street analysts from

First Call/Thomson Financial

.

Compuware said its software sales fell short of expectations, but its consulting services business performed as expected, even though margins in the service business will be negative.

"We are very disappointed with our software sales results," said Beth Chappell, executive vice president of investor relations at Compuware.

In afternoon trading, Compuware finished down 1 3/32, or 11%, at 9 5/32.
