Win2k

I've recently purchased a CD printer and when I installed it I got ahead of myself. I hooked up the printer first before I installed the software and now I can't install the software. The error message that I was getting was that it couldn't find Ezusb.exe so I downloaded and installed it to no avail. I removed the drivers and Ezusb.exe but still can't install the software. So is there a way to fix this or do have to reformat my drive and start all over agin? I know the software works because Itried putting it on my friends machine and I had no problems. So something is still flowting around my machine preventing me from installing the software.
