It happened on one system one time, and after uninstalling/reinstalling on the same system, it worked fine. I tested a few times after that, and it worked fine. Hopefully it will be OK from now on.
However, I'm having a different problem on a different system now.
I am attaching the logs and screen shots.
Basically- when I look at the UltiDev Web Server Explorer, the entry for UltiDev Web Server App Redirector is green, and the entry for Default Shared Host Process is red, and cannot be started.
The UltiDev services are all running properly.
