Cannot run CB on win7

Hi there
I’m facing a very weird situation
My system is win7 home sp1, ssd 256GB, 8GB ram
I log as administrator and I’m the only owner of my destop.
Already installed Cav last version.

I deciced to install CB last version from original link
Installation steps is ok. But after restart I cannot run CB
Link on desktop does not open, nor the CBU.exe in the installation folder.
I also tried to set “run as administrator” inside exe properties, but nothing.

I can only see in task manager the CBU.exe running, but no window opens.

Already tried on a different desktop, with similar hardware configuration.
Win7 sp1, 4GB, ssd
I have the same identical issue.
Link on desktop does not open, nor the CBU.exe in the installation folder.

Tried to chat with support, but today none replied.
Is there anyone with similar issue??
