I'm not be able to install MSI packages downloaded from the Microsoft Reference Source Code Center.
The package installs first a compressed file that gets decompressed by the custom action. The custom action is an executable copied to the temp folder. McAfee VirusScan Enterprise 8.7.0i prevents any program to be started from the temp folder.
How can I turn off this behavior?
By the way, McAfee VirusScan Enterprise protects its services, so I (as an administrator) am not be able to stop the services.
