Re: How do I uninstall Dragon Age Inquisition BETA?
I presume you did the "advanced" set-up for the Beta, which means you didn't do a completely new install but just the changed / additional files. (if you did a full "separate install", then you can indeed "uninstall" that one.)
So you should have two different sets of folders under "\Program Files (x86)\Origin Games". One; "\Dragon Age Inquisition", and another; "\Dragon Age Inquisition - Beta".
a) Simply Delete the "Beta" one.
b) Use a registry clean-up utility (I use the free "cclean", but there are others) to remove the orphaned pointers.
c) Set the DAI Beta title in your EA/Origin "My Games" to "Hidden". (Even with a Game Advisor's help, I could not get the title removed completely from my account.)
Good Luck!
