Symptoms

Consider the following scenario:

•	You have Windows Internet Explorer 7 installed on the computer, and you have the Microsoft Internet Explorer 6 version of hotfix 929969 installed on the computer.
•	You successfully install the Internet Explorer 7 version of hotfix 929969.
•	Then, you try to remove the Internet Explorer 7 version of hotfix 929969.

In this scenario, you cannot remove the Internet Explorer 7 version of hotfix 929969.

Cause

•	Before you install the Internet Explorer 7 version of hotfix 929969 When you examine Add or Remove Programs, you find only Internet Explorer 7. This expected behavior. Internet Explorer 7 hides the Internet Explorer 6 version of hotfix 929969 in Add or Remove Programs.
•	When you install Internet Explorer 7 version of hotfix 929969 When you successfully install the Internet Explorer 7 version of hotfix 929969 successfully, it is considered a reinstall of the same package as the Internet Explorer 6 version of hotfix 929969. However, the Internet Explorer 6 version of hotfix 929969 is still on the computer, it is only hidden. This is because the Add or Remove Programs registry keys contain information for Internet Explorer 6 and Internet Explorer 7.
•	When you try to remove the Internet Explorer 7 version of hotfix 929969 When you install the Internet Explorer 7 version of hotfix 929969, the release version of Internet Explorer 7's Vgx.dll file is not retained.
