3.11.0.9 not working: Installs to VS 2017 Buildtools directory

When updating NCrunch from 3.7.0.7 to 3.11.0.9, on Visual Studio 2017 Community 15.4.3, the installer put it to:

C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\Common7\IDE\Extensions

Of course Visual Studio didn't find it there, so everything went wrong (extension could not be found, activitylog.xml refers to old directory from 3.7.0.7, followed the instructions in the forum including devenv.exe /setup, now everything's gone, no ncrunch menu at all, and so on). Only a manual installation to

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\Extensions

could fix it. So everything's fine now, for me the problem is solved, but I'm not sure why this happened and whether the installer should be fixed.

Hi, thanks for sharing this issue.

This is a known problem caused by the limitations of the MSI installer. See here for other reports - http://forum.ncrunch.net/yaf_postst2272_Installing-NCrunch-on-nicknamed-multiple-installations-of-Visual-Studio-2017.aspx. We're aware of it and hope to eventually resolve it, but for now if you have multiple VS2017 instances installed, you'll need to install NCrunch manually.

Apparently the build tools is considered by the system to be a different instance of VS2017, so the installer considers it a candidate for installation.
