I have VS 2015 and I have installed Wix v3.10 but when I try to build the setup project it shows me this error:
The WiX Toolset v4 build tools must be installed to build this project.
I don't want to install wix v4 because it's not stable yet.
How I can get rid of this error?
回答1:
Had this error too with VS2017 and WiX 3.11.
I had added WiX Toolset v4 Setup Project as a new project in my solution instead of WiX Toolset v3 Setup Project. I kept getting the same error upon build.
So I added a WiX Toolset v3 Setup Project to the solution and *deleted the WiX Toolset v4 Setup Project (the error remained until I deleted WiX Toolset v4 Setup Project).
Now the error is gone, the build works and my Installer works. Is this the same problem on your side? Here's a screenshot that might help illustrate: Add New Project window

I created an .EXE with WiX 3.x (I forgot its version) in VS2012.
Then, I installed VS 2013 (I installed WiX 3.10). The same error occurred. Then I copied the contents from yourProduct.wixproj from the previous version of my Wix project to the newer version, no error occurred.

I had the same problem in Visual Studio 2017, I was using Wix 3.11 with V4 project from the Visual Studio project template and so this problem occurred.
I removed the v4 project and selected the v3 project template. This solved my issue.

Resolved the issue by installing WiX Toolset build tools
Faced the same issue. In my case, I had installed VS2017 extension of WIX and thought it was sufficient. But, WiX Toolset build tools must be installed to trigger the build from VS which means the extension needs WiX Toolset build tools.
