Restart Manager functionality in WiX 3.5

Heath StewartSeptember 16, 2010Sep 16, 201009/16/10

WiX 3.5 provides features to integrate with Visual Studio 2005, 2008, and 2010. But like many add-ins, since new files are being added they certainly can’t be in use by devenv.exe. So when we call devenv.exe /setup as part of our install, the changes may not show up in running instances of Visual Studio. To provide a better experience – ...

WoW64 is optional in Windows Server 2008 R2 Server Core

Heath StewartNovember 6, 2009Nov 6, 200911/6/09

Installation bootstrap applications are increasingly common as products chain dependencies like the Microsoft .NET Framework. Because 64-bit Windows supports both 32- and 64-bit execution, but 64-bit executables on 32-bit Windows give what some users might consider cryptic error messages, installation developers often ship a 32-bit bootstrap ...

Why Windows Installer May Require so much Disk Space

Heath StewartJuly 25, 2008Jul 25, 200807/25/08

Windows Installer is an engine for performing transactional installations. When installing a product for the fist time, most often few or no files to be installed are already present on the machine. But when upgrading or patching a product, most often those files are replaced so copies must be kept if an error occurs and the installation needs...

Windows Installer 4.5 Beta 2 Available

Heath StewartApril 1, 2008Apr 1, 200804/1/08

The Windows Installer team released Windows Installer 4.5 Beta 2 recently. While not a lot has visibly changed since the first beta for which I provided an overview, it's important to note that a new column was added to the CustomAction table since changes to column types are not supported in a transform or patch but adding a new column is ...

Debugging Custom Actions: Leaked Handles

Heath StewartFebruary 12, 2008Feb 12, 200802/12/08

Debugging custom actions isn't exactly the easiest action to do; Windows Installer spawns separate processes - remoting servers - to run in-process custom actions. Any opportunity to diagnose issues without debugging can be helpful.For example, an issue that comes up from time to time is leaked handles. A Windows Installer debug log might show...

Different Packages are Required for Different Processor Architectures

Heath StewartJanuary 15, 2008Jan 15, 200801/15/08

A common question is how to create a Windows Installer package that installs 32-bit binaries on 32-bit platforms, and both 32- and 64-bit binaries on 64-bit platforms. If you're actually trying to install 64-bit binaries to appropriate directories and write to the 64-bit view of the registry, the short answer is that you can't build a single ...

ResolveSource Requires Source

Heath StewartOctober 25, 2007Oct 25, 200710/25/07

It might be tempting to schedule the ResolveSource action, but ResolveSource actually requires that the original installation source is available whenever it is called. If your installer package is authored correctly, source must only be resolve in cases where the original RTM files are missing or during some patch uninstall scenarios. To ...

EXE Custom Actions are Bad

Heath StewartOctober 24, 2007Oct 24, 200710/24/07

Windows Installer custom actions that launch executables (base custom action type msidbCustomActionTypeExe, 0x2) are typically bad and should be avoided. How are they bad? Let the Windows Installer team count the ways.During internal audits we question any EXE custom actions (CAs) but inevitably some make it into the product. Typically these ...

Heath StewartAugust 27, 2007Aug 27, 200708/27/07

The What's New section of the Windows Installer 4.5 CHM available in the downloads section of the Windows Installer 4.5 Beta Connect site has technical details of new functionality and changes as usual, but now that we can talk about Windows Installer 4.5 I wanted to provide an overview of the new functionality. I'll be detailing several ...
