Win 7 64:
When I try to run QU11-108 I get an error message saying that it is not a valid Win32 application.
Your download failed. Make sure you entered the proper password (assuming you are using the registered version) and make sure you don't have a firewall program blocking the download. Also, sometimes when your security level is set too high, Windows won't let you download from password protected sites. In either case, that message indicates that you didn't get the whole file when you downloaded the install.
