I de-installed/re-installed VS 2015 Python support (directly from PTVS 2.2.4 VS 2015.msi). Same error.

What to do? The Machine (Win 10) has Python 2.7/x64 in PATH.

There seems to be a real problem for other too. See here: Visual Studio Python Environments window does not display

Interestingly, I have two similar dev machines (Win10/x64), both installed recently, both have VS 2013Pro + VS2015 Community installed. On one box, everything works fine, on the other: see above.

  • I received the same error as well when I tried to install the June update for PTVS. It removed the March install and then started giving the error. I didn't choose to install Update 3 yet. – Cindy Jayakumar Jul 12 '16 at 12:39

Had the same issue. Visual Studio 2015 Update 3, PTVS 2.2.4

Resolved it by:

  1. Closing VS
  2. Clearing the content of C:\Users\YOUR_USERNAME\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache folder. * notice the YOUR_USERNAME and replace it with your actual username to get the local path.
  3. Relaunching VS.

Hope this helps

Delete the contents from the following folders:

C:\Users{user}\AppData\Local\Microsoft\VisualStudio
C:\Users{user}\AppData\Local\Microsoft\VSCommon

and run Visual Studio 2015 again:

[x64] C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE
[x86] C:\Program Files\Microsoft Visual Studio 14.0\Common7\IDE

It seems like they fixed these issues in PTVS 2.2.5: github.com/Microsoft/PTVS/issues/1411 and github.com/Microsoft/PTVS/issues/1415

Control Panel/Uninstall change Select VS2015, click change

Once the dialog builds, select modify, then select Python tools.

Done.
