Hi,
I had TestStand 2016 working, then I added 2017, it was also working. After I added and removed 2010 version of teststand (due to customer's version being 2010), I cannot launch any teststand versions.
The version selector would error out, so I cleaned up all versions, and removed version selector manually. Now I am completely screwed, I can install 2017 or 2016, but they won't run, and I cannot find version selector anywhere...
I need help with this issue
