The 'TestWindowPackage' package did not load correctly #172

Closed NickeZ closed 6 years ago

NickeZ commented 6 years ago

I get the following error when trying to open the "test explorer" after installing the GoogleTestAdapter. The problem goes away if I disable the plugin.

I attach the information I can extract about the system and the error log. Unfortunately the error log is not formatted nicely. I don't know how to get a nice formatted output from the xml file.

The 'TestWindowPackage' package did not load correctly

The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file 'C:\Users\niklas\AppData\Roaming\Microsoft\VisualStudio\14.0\ActivityLog.xml'.

Restarting Visual Studio could help resolve this issue.
