I just installed the 64-bit Win7RC, and I can't install programs on my user account(the default admin account) - it says I have to run the program as an admin. WTH!? I am the Administrator!!!!!

Okay, so apparently, the "default" account says it is the admin account, but it isn't. I had to create a second account as an administrator, and it lets me install programs just fine.Is this a bug? or just a feature;)

Just Installes The rc x64 and Windows won't let me do anything. I am the Administrator. I can't even ad more accounts as stated above. Well, just reinstall and see what happens.

you might want to check the ownership of the directory/drive you are trying to install into. older windows installations can leave behind their security settings on other drives/folders

Well that's out of the quistion as it was a fresh install on a new (never used) computer. Installing the x86 version solved the problem for now. The problem with the Admin rights occured when lowering the UAC sensitivity. Could even click the uac after that change. Or anything else. Formatted the disk and did another fresh install of the x64. Same problem.X86 works without a problem.
