I get this error after downloading the current version of iTunes64bit onto my brand new out of the box Toshiba Satellite A505 with Windows 7 64 bit and trying to run it.
I tried the 32 bit version, and of course the error I get is "This iTunes installer is intended for 32 bit versions of windows..."
After I got the error the first time on the 64bit download, I deleted it and downloaded it again to make sure it wasn't corrupted. I ran it as administrator and as a regular user and still got the same error.
Any and all help would be greatly appreciated!
