After installing Test Studio trial and unistalling again after the trial period has ended, I am left with an error message each time VS2015 Community Ed opens.
"The 'WebAiiVSIP' package did not load correctly" which is detailed in VS error log:

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

So it looks like VS2015 is still looking for a component of Test Studio.
The extension is completely uninstalled (not listed under extensions and the directory C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE does not contain any files or folders with Telerik in.
I'm opening this support ticket as suggested by the Telerik team:
Hey Thomas!
I connected with my engineering team, and it appears this is something we haven’t come across before:
This would indeed not be an expected crash and we failed to reproduce the problem on our side.
Since you are still struggling though, it is possible that even after the uninstall there is a process still locking something. This exact package from the error message should be located here:
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Telerik\Test Studio
Would you check for any left overs to remove there and also search in C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE for any similar files.
In case there is nothing, then would you please restart the machine?
If all this shows no result, my advice would be that you open a support ticket or a forum and share all details, so that that the support team could advice further.
