How to disable MSI Windows Installer auto-repair ?

www.exetools.com - How to disable MSI Windows Installer auto-repair ?: "The problem is that when a program using MSI installs it registers itself with Windows Installer Service. The service then controls certain program properties. You cannot stop a certain program from using the Repair option. However, you can disable the service all together by opening up your registry and going to HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer (you may have to create this folder) and Create a new DWORD value, or modify the existing value, called 'DisableMSI' and set it according to 2 = disabled. Exit your registry, you may need to restart. This will almost definately fix your repairing issues. The only problem you will face is that this disables the MSI service for all applications."
