Open up your task manager (Ctrl-Alt-Delete) and shut off anything running that looks like ProSeries.

I've gone through all the processes that are running and can't find anything that looks remotely like ProSeries. 

Have you tried rebooting your computer?

Have you uninstalled 2014 already - if not, do that first then maybe your error for 2013 will disappear

👍 Lisa, or maybe just get a new computer with Windows 11 and you'll have a lot more speed and space... Just my opinion

Yes, and just did it again but still no luck. I've decided not to worry  about though, I'm just going to leave them. Thanks!!!

Yeah, OK I'll just leave things alone and look into a new computer. Thanks.

You're welcome. I just had to do the same thing so if you have any questions just ask us.

I had this same problem.  While deleting running tasks in the task manager may do the trick, there's an even more sophisticed solution that has to do with "lock" programs.  See the following:

Good luck,
