Hello, I was having some problems launching ArmA 2: Combined Operations from Steam, I searched the web looking for a solution but there was nothing that solved my problem. I decided to take matters into my own hands and fix it myself using some good ‘ol DOS knowledge.
Here is my post from the another ArmA forum post:

So I started looking for reg.exe and found it’s location and then edited the “_runA2CO.cmd” batch file to include the location of the reg.exe file as there is obviously a path issue with reg.exe on my computer. And so I replaced everywhere where it says “REG” to: “C:\Windows\System32\reg.exe”, and it seems to work! This is the only change I’ve made but I hope it helps some of you.
