In last week's release some changes to patching with WiX were made with more exciting changes to come. Peter Marcu has implemented some changes he'll talk more about on his blog, but suffice to say has reduced the number of commands and command line arguments required to build a patch.I've added some documentation for the new the patch build system...

The documentation for the WriteEnvironmentStrings action states, Note that environment variables do not change for the installation in progress when either the WriteEnvironmentStrings action or RemoveEnvironmentStrings action are run.

Any changes made in the transforms affect the aggregate view that Windows Installer reinstalls. This is displayed in the diagram below, where the bottom layer is the components in the product MSI, the s...

It removes, if present, the culture in the URL so that when a reader clicks the link he or she sees the content on MSDN in their preferred language if a translation is available.So, http://msdn2.microsoft.com/en-us/library/aa372866.aspx&nbs...

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 and jsc...

To write an installer for your PowerShell snap-in, the PowerShell documentation instructs you to extend the PSSnapIn or CustomPSSnapIn class. When you add your snap-in assembly to the Custom Action view in a Windows Installer Project in Visual Studio, the InstallerClass property should be set to True and your installer class will be run when the Wi...
