Deleting Reg Key

Have you tried deleting the sub keys one at a time starting at the bottom one, then delete the main "Bohemia Interactive Studio" key?

Is this the beta Arma 2?
Is it the Steam version?

I searched "uninstall Arma 2 OA" at BIS forum and there are a lot of considerations. but it seems as though you can manually remove BIS. I'm not familiar with BIS or Arma 2, so I can't gve you exact instructions.

It might be worth a try to reinstall and then uninstall.

Applications create Registry keys when installed. From your screen shot I gathered that the key was related to the game.

Ok, non-steam from Amazon. That eliminates about half or the posts over at the BIS forums. Have you looked through some of the posts on the link I provided?

The methods everyone has given here should work. Esepcially post# 10 - one thing that might not have carried forward is:
When you type regedit in the start menu search, you have to right click the result and select run as administrator

I'm not talking about the game...I'm talking about the Key...nothing to do with the game. This is a non-steam CD I bought from amazon.

The link worked for me, that's how I got the above URL. If clciking on the URL doesn't work, copy the entires line and paste it into the address bar of your browser.

What is the top level key?
in an elevated command prompt
type:
reg query /s "top level key" > %userprofile%\downloads\ProblemKey.txt
exit command prompt and if the txt file isn't too big, post it on the thread
otherwise, place it in a zip file as an attachment

If I fat fingered the example and the text file doesn't exit or is empty, try it again, this time copying the output off the command prompt window
