Multiple ArmA2 Installations - which serial?

[tomturner 10]

I purchased:

1 copy Arma2 - DVD Retail

1 copy Arma2 - Amazon

2 copies ArmA2OA - Amazon

Installed ArmA2 + OA on one machine 4 months ago but have not needed to install on second machine until today. My son is coming home from Afghanistan and I am getting the second computer ready for him to play with me.

My problem is that I don't remember which serial numbers I used on the installed one and which are available now for installing on his computer.

Is there a way to resolve this without reinstalling on the completed one? It is already completely patched with all my addons, etc.

Please help, thanks.

A conundrum :)

My only advice would be to install the second machine with your best guess, then check the key in the registry. If it's the same, uninstall & reinstall on the second machine. Still a PITA, but not as bad as redoing the first machine also :)

Registry key for ArmA2 can be found using regedit.exe, look under:

HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/Bohemia Interactive Studio/ArmA2/KEY
