Copying Starcraft 2 to another pc problems

Copying Starcraft 2 to another pc problems

I am trying to get another pc battlenet to see the copy starcraft 2 files through battlenet but what ever i try it just wants to redownload the whole game. Both battlenets own the game and my internet is painfully slow so downloading the whole game again for some co-op is a nightmare.

Edit to clarify i have tried to scan and repair but that does nothing im sure its in the right place

2nd Edit just tried to move the files then have battlenet scan for games and it seems unable to see the starcraft 2 files at all.

3rd Edit gona uninstall battlenet then re-install dosnt fix it

4th Edit having it scan my hard drive across the network and it see’s the folder then.

5th Edit runing SC2Switcher.exe which has prompted a 3gig download. will report back after that lengthy download has finished

6th edit so after running sc2switcher and a 3gig download now its launching the game but only from that exe trying to launch it in battlenet still wants it to update the entire game
