Hi Tomas, You're likely right, I didn't restart, unplug/replug the hard drive, or even close CMD, so I can give that a go. Thanks for your insight.
In any case I think I'll go with the solution of using 3.5.1 as it seems to solve the issue, and would mean I wouldn't have to modify hard drive or registry settings on my user's PCs. Many thanks, Marc P.S. I accidentally didn't include the r-help address, I'll bring it back in in case others might find this useful.
