Temp X: drive

[japitts]

Hi all,

I'm using a computer (Win98) that used to be on a network
(no longer) and I'm trying to update MSN Messenger and I
get an error that says something about the X: drive
unavailable. I remember a long time ago someone telling me
that I had to make it a temp directory in order to upgrade
to the current version. Does someone know the DOS command
to do that? Or, another to get around it?

Thanks so much in advance!
