That's quite strange davidm. :shock: I have 32-bit Premium SP1 fully patched, w/UAC disabled and I can do everything I used to do in XP with Eraser. Currently I have 5.86. Did you install with UAC enabled ? Unless that is something specific of Ultimate which I doubt, folder redirection might be the problem, try install with UAC off. If that doesn't fix it, you can try 5.86, which is working for me without issues.
