A friend called me about a problem he's had installing iTunes on his laptop (hxxp://www.apple.com/itunes/download/). The laptop is XP Media Centre. He tried to install iTunes whilst logged on with Admin rights and he got an error message saying that there was no J: drive so he was unable to complete the installation. He's not partitioned the hard drive or done anything "clever" (by his own admission he's an IT novice!). I had him check in Disk Management and it only shows his C: drive.

I downloaded the same executable to my XP Pro SP3 and started the installation process. It didn't whinge about the J: drive (no, I don't have a J: drive) so it can't be a problem with the executable.

I did some research and came up with the suggestion of creating a virtual drive (subst j: c:\<MyNewFolder>) but I've never tried this and do not know if it's likely to work or if it might screw up his system. Does anyone have any ideas?

I'd add that he lives a couple of hours drive from me so I don't want to give him some instructions that might get him into bother, requiring me to have to visit him to try to resolve any problem that I might have caused.

Thanks for your time.
