I recently built my first system everything went well with the exception of getting my old Office jet 600 back on line. The orginal start up disc did not have the drivers for winXP so I purchased a new start up disc from HP for winXP. When I tried to install it I got the message that a previous version of the software exists. When I went to " uninstall software " and tried to remove it. I got a message that the following file is missing and I can't complete the uninstall " C:\Program Files|Hewlett-Packard\HP Officejet Series 600\uninst.Isu " . I really need to be able to send and recieve faxes etc... and I still haven't figured out what I need to do.
