When you attempt to install any application, the installation may stop and you may receive the following error message:
The Uninstall Shield is in use. Please stop the Uninstall Shield and try again.
This behavior can occur when the permissions on the Uninst.exe file and on the C:\Winnt directory are not set correctly.
To resolve this issue, set the permissions on both the C:\Winnt directory and the Uninst.exe file to:

Administrators\Full Control
System\Full Control
