I just updated my computer to Windows 7 64bit. I had reinstalled curse-client because it failed to open. I then tried to re-intall all the addons I had on and it would download 100% and then it would try to unzip files and immediatly say installation failed. My addons were not working before the reinstallation on curse-client and now I cannot seem to reinstall them. Can anyone help me determine what is wrong and/or what to do?
Right-click the WoW shortcut and click "Open file location". If it's in "c:\Program Files(x86)", "c:\Program Files", or "c:\Users\Public", move it. Win7 has these locations locked down so that only "real" users can have read-write access to them.
Post a ticket from the Curse Client after attempting to update so Adamar can see your log file. I suspect it's a permissions problem. You can add the Users group with full access to "C:\GAMES" via the Security tab on the folder's properties dialog.
