After installing the last several releases of Visual Studio, you’ll find shortcuts to command prompts that automatically set up the PATH, INCLUDE, LIB, and other environment variables.

Immediate Custom Actions Always Impersonate

July 12, 2007 Jul 12, 2007 07/12/07

Heath Stewart

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. This means, of course, that in over-the-shoulder elevation when administrative...

Windows Installer Errors 2738 and 2739 with Script Custom Actions

May 31, 2007 May 31, 2007 05/31/07

Heath Stewart

Windows Script custom actions should be avoided. They are difficult to debug, get blocked by virus scanners, and are far more susceptible to machine state than native custom actions. 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 ...

Custom Action Guidelines

April 20, 2007 Apr 20, 2007 04/20/07

Heath Stewart

Rob Mensching, father of Windows Installer XML (WiX), blogs about why managed custom actions are a bad idea. Aaron Stebner follows up by saying (and has said before): How do you know what's natively supported? Those who know me already know what I'm going to say: read the docs.

Mitigating Custom Action Problems for Patches on Vista

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

Heath Stewart

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.
