Problem with Visual studio 2019 integration as non-administrator

[Søren]

Hi,

I have been using Justmock for years now without any problem. But lately we started running as our normal users and not as local administrators on our PC's.

When installing Justmock I'm using an elevated admin account and it seems to complete without any errors, afterwards I'm starting VS19 as my normal user and are presented with the dialog shown in the attached file.

The log shows that the assembly could not be found or loaded, when looking in the folder specified in the error, I do not have an <extensions> folder at the location. So I assume that installing the product with my administrator access does not work for my normal user, what to do? 

The activity log shows the following error:

690 ERROR CreateInstance failed for package [JustMockPackage]Source: 'mscorlib' Description: Filen eller assemblyen 'file:///c:\users\foobar\appdata\local\microsoft\visualstudio\16.0_4cd0081b\extensions\alz4b0wd.jii\Telerik.JustMock.VS2017.dll' eller en af dens afhængigheder kunne ikke indlæses.

I had success with an uninstall of VS and Justmock, rebooting and then reinstalling VS and Justmock again.

The observation was that the extensions was located in the admin profile and not in my current user and thereby causing Justmock to fail. Prior to uninstalling VS, I tried just to uninstall/reinstall Justmock and it was the same behaviour.

Hello Søren,

I tried to reproduce the described scenario by installing JustMock to non-admin user using elevated admin account but everything worked fine on my end.

From what you have reported my bet would be that probably the Visual Studio instance became corrupted - maybe some registration of a previously installed version of JustMock remained registered after its removal.

Please let us know if you notice this behavior again.

The reinstall worked, but one of my colleges still had problems, but we found that it was an issue with corrupted files in extensions.

The Solution was to run %programfiles(x86)%\Microsoft Visual Studio\Installer\resources\app\layout\InstallCleanup.exe with the full  option. To ensure that all files were removed before reinstalling VS again and now everything worked as expected.
