Bad CD Key given in setup

[xxhigor 0]

I used a CD KEY unofficial and played for a long time, but started giving this error Bad Serial Number Given In Setup, after this I desintalei the ArmA 2 and OA 2 ArmaA the folder and bought the 2 official games on Steam, downloaded and installed and the error persisted, I've tried various methods and did not work, the error persists should I reinstall? I need to do something else before reinstalling?

 

In my opinion my unofficial guess this key interrupting the Key of Steam or something, I do not quite understand.

 

 

I use my PC as ADMINISTRATOR and not as a registered User.

 

 

Thank you and sorry for the English

Maybe the problem is in the registry. Try to delete all Arma 2 registry files and reinstall.

 

Hope this works!  :)  :beans:
