Resiliency is the ability of an application to recover itself from a damaged state. The state may have been caused by a missing or incompatible file or registry key. Although Microsoft does not generally recommend disabling the Windows Installer, there may be situations in which it is advantageous to do so.
One way of disabling the Installer is to use the DisableMSI (Type REG_DWORD) policy. This policy will disable the Windows Installer, thereby stopping resiliency. The policy is set through the registry key
If this policy value is set to "0" or any other number other than "1" or "2" or is absent, the Installer is always enabled.
If this policy value is set to "1", the Installer is disabled for nonmanaged applications but is enabled for managed applications. This setting does allow an application to be advertised to all users of a computer but does not allow an application to be advertised to the current user.
NOTE: While this policy is set to "2" you will not be able to perform an installation or use any function of the Windows Installer.
