Hi,
I have been using TestStand 2012 for a while now, and just recently installed 2014. I kicked the tires on 2014 and it looks good, but I wanted to launch 2012 again to look at some stuff that is linked to that install. I tried to use the version selector to go back to 2012 but when I try to launch it I get an error (attached). I actually still have 2010 installed as well ( forogtten about it), and tried to launch that after selecting that version and it launches fine. select 2014 again and that launches fine. But I can't get 2012 to open anymore. Any thoughts?
