I’ve tried suggestions to fix it, but it didn’t work for me.
When I tried to create another administrator account - under that account I was able to update and run game, but when I relogined to my original Windows account I still get error message. It’s frustrating as under another account all works.
I’ve tried also to uninstall Battle.net application and install it again, also tried to re-install game - still get this error.
I assume that inside Battle.net application some module is forced to be executed under normal Windows account permissions not administrator ones.
Update:
Just tried solution from here - remove HotS folder from Documents and Settings - and I was able to play HotS.
Just need to configure options as they are lost.
And it seems like I hit another problem - as it tries to update each time I start game, but it still playable.
Good luck guys and have fun!
