Uninstall hangs in Vista.

[Simon_Yang]

I created an MSI basic project. In a subfolder of my install folder, I had 50000 small files. Everytime when I unintall it on Vista, Windows Installer hangs. From uninstall log, I saw it pended on action InstallValidate. Below is uninstall log:

This behavior never happened in WinXP.
Anyone has idea about this?
Thanks in advance!

InstallValidate is a standard Windows Installer action. One task that it performs is checking to see if any files included in the install/uninstall are in use. With 50,000 files, this may take quite a while (on Vista, more is involved than what would appear to be a simple in-use check, possibly due to the changes for the Restart Manager support).

Since this action is built in to Windows Installer, we do not have any control over how it operates, nor can we determine exactly why it is taking so long. You may try contacting Microsoft for further assistance with this behavior.
