Error message when starting Studio 2015 SR3 (Object reference not set to an instance of an object)

Hi all,

Since one week I get an error message when starting Studio 2015 (SR3). See the end of this post for the full message. After clicking OK, it opens rather minimized. Most actions/clicks after that will also lead to an error. Although always an "Object reference not set to an instance of an object", it's not the same <type> or <Source> each time though.

I have tried repairing the installation, removing/reinstalling it etc. to no avail. When uninstalling first, I also remove the usual suspects:

  • %USERPROFILE%\AppData\Local\SDL\SDL Trados Studio\12\
  • %USERPROFILE%\AppData\Local\SDL\SDL Trados Studio\12.0.0.0
  • %USERPROFILE%\AppData\Roaming\SDL\SDL Trados Studio\12
  • %USERPROFILE%\AppData\Roaming\SDL\SDL Trados Studio\12.0.0.0
  • %USERPROFILE%\Documents\Studio 2015\Project Templates
  • %USERPROFILE%\AppData\Roaming\SDL International\Sdl.Enterprise.CredentialProvider.xml
  • %USERPROFILE%\AppData\Roaming\SDL International\Sdl.Enterprise.ServerConnectionManager.xml
  • %USERPROFILE%\AppData\Roaming\SDL International\Sdl.ProjectApi.CustomCredentialProvider.xml
  • %USERPROFILE%\AppData\Local\SDL International\Sdl.Enterprise.ServerConnectionManager.xml
  • c:\Program Files (x86)\SDL\SDL Trados Studio\Studio4\

 

When installing a previous version (2014) I get the same error.

I have run out of ideas.

Anyone..?

 

Thanks & regards,

Richard
