Latest viewers not getting installed

This is happening with both SL and FS, keep getting this message despite downloading the latest versions again and again.

Sitting here with a clean install of windows Vista 64 bit. Downloaded SL viewer and Fire Storm, none of them works.

No need to clear my cashe since its a brand new install of that as well.

Any other viewers to reccomand that might actually work?
