I just tried it again. The anti-keylogger still won't work and it appears it was designed to run on a system with Admin privileges because it will prompt me every time I log in or boot on my standard user account.
My setup is multi-user and I was struggling to run the program when I switch between multiple accounts. One will block the other when you switch between accounts and give you an error.
As I said I'm a big fan of their work. If you can, try to get the best features in Riot Isolator separately: Ghostpress - Anti-keylogger and ScreenWings - Anti-screenshot..
Each takes about 3 MB RAM which is nothing. The harder thing is to tame them when you use more than one Windows account because the way it hooks into the system to prevent even the deepest intruders from spying on you.
