Immediate Custom Actions Always Impersonate

Heath Stewart July 12, 2007 Jul 12, 2007 07/12/07

Windows Installer is a client/server application. When you install a package using msiexec.exe - which is executed by default in response to shell verbs such as Install - or APIs like MsiInstallProduct the package is initially processed under the user's credentials.

Windows Installer Errors 2738 and 2739 with Script Custom Actions

Heath Stewart May 31, 2007 May 31, 2007 05/31/07

That is indicated by Windows Installer error messages 2738 and 2739, which read: As some people have found, re-registering the runtime libraries vbscript.dll ...

Mitigating Custom Action Problems for Patches on Vista

Heath Stewart October 25, 2006 Oct 25, 2006 10/25/06

Because some of the custom actions in Visual Studio 2005 are authored to impersonate the non-privileged token of the invoking user on Vista, a mitigation has been checked in for the patch wrapper that is used to add additional compression for the patch and to patch multiple products, if present, without rebooting in between.
