There's something weird going on, and, despite negative antivirus and malware scan, I'm smelling poo.... I tried to download it again, always from the link Motley provided... well, when it asked if I wanted to overwrite the existing file I said yes, Firefox downloaded it again but, instead of overwriting, it created new files, a supersetup(2).exe and a supersetup(3).exe. All of them of 0 bytes of size. I can't delete any of them, not even after rebooting, because system keeps saying some program/user is using those files.... what the hell is going on?
1plus44, I'd like to try what you said, but the dang Windows will tell you that another program is using the file, not what program is using it... so I can't shut down anything!
