How to fix the Darky Key Changer Error

***All credit goes to 'enimabag'*** He never posted a new thread about this so I just decided to do it.

How to fix the "Error code 5" "Error Message: Access denied" error message:
__________________________________________________ _____________________________________
1. Open Regedit
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2 OA
3. Right click on the ArmA 2 OA folder and hit permissions
4. Then hit advanced
5. Remove any profiles in the list that it lets you. (the important ones are greyed out and won't let you delete them)
5. Hit apply and try Darky again

Bro. I love you. (nohomo) <3

worked for me <3

I didn't have any to delete. And I'am getting error 0.
Any help to fix it?

LOL been posted a few times just not in this manner, all you do is go to Permissions > Advanced > and make sure Set Value isn't set to DENY, if it is uncheck deny and hit ok then change your key, and re-check DENY again so you can launch OA through steam and not have steam change your CD key back.

LUVE YAH!! NO HOMO MAN! it Worked!!
