Why UnityPro V12. doesn't open?

[jhonut1]

Hi,

I installed UnityPro V12. I have installed it without any error. When I want to open it, nothing happens. What should I do to be able to open it?

PS: I had instaleed it a while ago, but yesterday I installed EcoStruxure Control Expert v15. It unistalled my UnityPro. Now I want to come back to unity pro. I installed it but I am not able to open.

Did search on the Internet, and found: EcoStruxure Control Expert (Unity Pro).
So, it looks like Unity Pro today are the same as EcoStruxure Control Expert.

And, it is not common to be able to have more than one version installed, so my guess is that you can not have both.

Thanks for replying! I know I can't have both because when I installed EcoStruxure Control Expert over UnityPro, the last was uninstalled automatically. My problem was that after removing EcoStruxure Control Expert and reinstalling UnityPro, it didn't open. To make it work again, I had to restore Windows to a previous version.

Do not know that program, however if it has like shared DLL files, you may have got newer once, and if shared, they may not be un-installed, and the old program not working with the newer files...
Restoring puts it back to the old status.
