Bad Serial Number Given in startup

[HaloGuy212 2]

I found out on how to fix this with regedit but every time I try change "Subkeys only" to "This key and subkeys only" and hit apply or ok it goes back to "Subkeys only"

 

I followed this this tutorial.

 

1, Run REGEDIT
2, Expand HKEY_LOCAL_MACHINE
3, Expand Software
4, Expand Wow6432Node
5, Expand Bohemia Interactive Studio Not Bohemia Interactive
6, Click ArmA 2 OA, If you only see 1 file named "(Default)" And type REG_SZ then,
7, Right click the ArmA 2 OA file and go to Permissions
8, Left click YOUR USER, NOT! Users
9, After selecting your user click on Advanced 
10, Yet Again click on your username for your pc and click on edit
11, In the drop down menu select This Key and Subkeys
12, You will see allow and deny make sure all allow boxes are ticked then click ok
13, you will be taken back one Dialogue box, Click Apply and OK and the same again on the
next dialogue box.
14, Now you should see 4 files sat in your ArmA 2 OA folder, Names, "(Default)" "Data" "Key" & "main"
15, Now play your game hassle free
