I have tried installing a PDF printer (CutePDF and Bullzip PDF) on a Windows XP Pro SP3 machine. With each software program, installation hangs and spoolsv.exe is always at 50% cpu utilization. I have to end the spoolsv.exe process and cancel the installation. All other printers, network and usb, run fine. I have tried running cleanspl to remove all print drivers and print monitors to start from scratch but nothing ever works. I can always reinstall USB and network printers after running cleanspl.exe, but when I go to install the PDF printer it does the same thing. I have tried deleting the c:\windows\system32\spool\printers folder contents as well. I am out of ideas aside from reinstalling Windows XP. All other XP machines on the network run fine with network printers and CutePDF installed, so I am baffled.
