Are you saying you don't even see an attempt to launch? No start-up screen? Nothing? Never seen that, but it could be an indication of something serious going on with your OS.

Have you tried launching by browsing to and clicking the .exe file?

You don't say what operating system you're using or how much free, clean, defragmented space is on your hard drive. But, assuming you've got at least 20-30 gigs of free space on your C drive -- I'd be very concerned.

Might be worth a complete Malware Bytes scan.
