Cannot open any program or download

Hey all
Recently installed the windows 7 beta today, having a few problems and after countless hours searching google for a fix i simply cant find any, so here goes:

- I cant open any programs, at all - im getting the error 'This program is not a valid Win32 Application' even when i have made sure it is.

- I can download files, but when they are complete the file/s are not there and the sizes are '0 kb'

- Also i cant make them appear on my desktop when finished downloading? Even if i run it in administrative mode.

Any help would be GREATLY appreciated.

- Sorry if this is in the wrong part of the forum, just hoping for a fast answer.

P.s. Also if anyone has any links for Soundblaster 5.1 drivers/anti viruses etc? I cant get any to work, even some that state as win32 windows 7.

Thanks again.

Had it on a disc, burned it a long time ago and never installed it

But how can you be sure this is the problem? Have you come across any of the above before? And is their anyway to check that is not the current version i have?

Yes, there are some reports on other forums. and with HACKED BOGUS
downloads in the area of 800K to over 1 million copies you surely could have one.

I recommend you get the latest version for MS, burn at 4x verify via MD5 and then clean install.
