Here are some things that worked for me when I got version check problems:

1. Turning off your firewall and try launching the game. (I use Bitdefender and this is major source of my issues)
2. Run a virus scan and check for malware. Malwarebytes +/- ADWcleaner are good adjuncts. Having malware installed may prevent the game from launching. Can also check your list of installed programs to see if any suspicious programs were installed without your knowledge.
3. CCleaner helps sometimes
