I have the same exact problem. It won't install. Same errors "Do not support this platform 0". I ran it again, and again and it finally started running the install but it never stopped. And the sound card does not work. Sabrent Sound card model SBT-SP6C. It doesn't work,. I don't want to waste money on it even if it was only TEN DOLLARS!! I got better things to spend $10 on.
And for some reason I think it is trying to setup the Vista drivers
for my Windows 7 Operating system. So, I navigated to the Windows 7 directory and ran the setup from there, rather than the top directory, and still, no workie.
Running setup.exe is easy. I ain't doing anything wrong. Btw, when I booted up after installing the card.. Windows 7 didn't even act like it saw anything new! Like no plug and play! I was like, hmmm.. thats odd.. It just gets worse from there.. The thing doesn't work right. Sabrent is
