"Great support by UgCS! We solved the problem using teamviewer. The beta needs a x-64 Windows, my laptop had x-32. Now I reinstalled windows, everything works fine.
Thank you Sregey an thanks to you Liliia! You made an excellent job."

"No chance. Even in the root directory happens the same mistake. I already wrote a mail to the support and told them what happens. Don't know if its a problem with the hardware but 2.11 worked fine. And that laptop is the one I always take with me in…"

"Its both win 10. I will try to install on the root directory.

Hello!
What operating system do you have?
If you have Windows 10, try to reinstall UgCS to the root directory of the hard drive (system drive C:\)."
