How to Enable WiX Projects in Visual Studio 2015

Update 2015-09-08: WiX Toolset 3.10 is released with official support for Visual Studio 2015 editions. It is available for download from wixtoolset.org.

You can manually enable Visual Studio 2015 compatibility with WiX 3.9 or earlier:

1. Copy
   C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\Microsoft\WiX to
   C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\WiX

2. Then execute as Administrator:

   "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv" /setup

   

When you open Visual Studio 2015, WiX 3.9 and earlier projects will be compatible.

This was also my issue before, and it looks like Chris Schiffhauer's answer isn't the best solution by now, as WiX 3.9 or earlier is not specifically build for Visual Studio 2015.

The solution is just to install the latest builds of WiX v3.10 from this link as what they replied on their tweets: https://twitter.com/wixtoolset/status/597796279729528833

I only have Visual Studio Community 2015 RC when I'm looking for a solution, and upon following Chris' answer, after installing WiX Toolset v3.9 R2, I didn't found the C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE folder nor the C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7 folder in my system.

I have found that the order of installation is important. Using VS2015, when I tried to add an existing WiX project I could not select it because the *.wixproj extension was not available. When I tried to add a new WiX project the "Windows Installer XML" templates were not available.

To fix this I closed VS2015, uninstalled the WiX tools using the Control Panel and reinstalled it by running wix310.exe (version 3.10.2.2516 downloaded from https://wix.codeplex.com/releases/view/619491)

1. If you have VS 2012 and VS 2015, Install Wix ToolSet V3.10.3. This will install the Wix toolset for 2012 and 2015 will not yet detect it.
2. Next in Control Panel-->Programs, choose the WIX installation, right click and change. Choose the Repair option in the toolset UI.
3. Once repaired 2015 starts detecting the installer and it works fine after.
