Tomas,
I just installed from Steam. It installed all the right files and runs fine on my Win 7 machine here.
The two files you referred to above:
..\SteamLibrary\steamapps\common\Command Ops 2\_CommonRedist\DotNet\4.5.1
..\SteamLibrary\steamapps\common\Command Ops 2\_CommonRedist\vcredist\2013
should be in the _CommonRedist directory, which is one of 14 sub directories. There should be a lot more other files in your Command Ops 2 directory. Here's a screen dump of what I have:
Can you please check your steamapps\common\Command Ops 2 directory for me and confirm they are not there. If they are not there can you please do a search on your system for CmdOps.exe and if you find it, tell me where its been put.
One other question. Do you already have Cmd ops installed from Lock N Load?
