Can't Open Client

Hello people, I need your help please!
I've installed client and when I'm clicking at the desktop icon nothing happens, same with wow.exe in the folder.
I've tried a couple of clients from different sources and also yesterday I downloaded TBC for another server and it went the same way.
Folder with WoW Classic placed in separate disk from actual WOD client. I added all exe files to excpetions in my antivirus settings. Turned it off. Tried different compatibility settings in properties. Deleted WTF and so on.
When I'm clicking on the icon I see only little loading mark appears next to the cursor for a second and that's it, nothing happens then. No even black blink on screen.
Please help me, and sorry for my English in case.
