I had posted a little while ago about upgrade issues. I think there is something about the account privileges. It appears that the default installation was trying to start the service as some local ./JetBrainsYouTrack user - that account may have issues.
I tried changing that to my AD account that has rights (it's how I run TeamCity as well) and it still won't start.
Just realized those logs I previously attached were from when V5 was running, not V6 starting up - where can I find logs for the failed start attempt?
