I just bought a new computer (HP pavilion w2408h vista 64 bit) and I cannot install Sandboxie, Returnil, or a vpn. I think XB2 has fixed this problem but I am using xb1. Torrentfreedom cannot be installed. My question is will first defense ISR be a viable alternative to Returnil? I know with Sandboxie and Returnil nothing is saved to the hard drive. Will First Defense ISR do the same? Or does it just return installed programs to their original state? I want everything kept in a clean state....including junk accumulating on my hard drive. Are there any other sandbox programs that will work with Vista 64 bit? Or should I just take this computer back? I am really disappointed.
