Six launcher will instal the game in the correct location in OA folder. When six launcher is used a big button with instal comes up on the left side of the launcher.

Anyone got any help for us? I had it working last week then something happened and it stopped working at all.

Right now I am not even able to instal the mod. I click on instal and it does nothing.

I have the same issue with trying to instal the game through six launcher. It sits and spins for awhile and then throws up that error. I am not able to instal the game. I have uninstalled six launcher, same with arma 2 OA. I am not sure why it is having an issue. I am also running it in admin
