F-Secure PSB Workstation Security 13.X installation fails at Windows 7 x64 OS. F-Secure PSB main exe setup doesn't even return error code back, it just runs about 5 seconds, then exits and returns code 0 aka success. When opening another log file in C:\Windows directory (cannot remember the exact file name because atm I don't have access to this system. I can post it later) I can see that the installation failed with error code 18. Can someone tell me what is this error code 18? Couldn't find any documentation.
