IE7 Update Doesn’t Work For Some PCs

Some users aren’t able to use Internet Explorer 7 (IE7) after installing this month’s six-bug patch, the Microsoft Corp. security team acknowledged late Wednesday as it published a work-around for the problem.

“The issue here is that after applying the update, these users may then see the ‘File Download Security Warning’ dialog box raised when starting IE,” said Christopher Budd, a program manager with the Microsoft Security Response Team in a blog post. “After you close the dialog, you then cannot start IE.”

According to Budd, the dialog box appears only on machines where the Temporary Internet Files directory, which is used as IE’s cache folder, has been moved. IE will not have the proper access rights to the folder in its new location and so will throw up the warning and refuse to run.

Although the IE team said it’s looking into the behavior, the MSRC has generated a support document with two work-arounds that users can apply to fix the problem. The first work-around is to simply return the cache folder to its previous, default location; the second is to grant the required permissions to the folder in its new location.
