How do you create a temporary virtual C drive?

[Queesh]

I can't find any links that explain it the way I need it. Software needs to install a program directory to the C: drive, but my main partition is F:.

I had a similar problem around 2 years ago. I added a simple line of code in the DOS prompt to make my F: drive read as a C: drive until a reboot. I just can't for the life of me remember how it's done.

I'm using Win XP Pro 32-Bit.

You should just be able to re-assign the drive letter in Disk Management. Go to Control Panel -> Administrative Tools -> Computer Management and Choose Disk Management in the left-hand pane. If you right-click on the drive it should give you the option to change the letter.
