Cannot install printer driver.

I am trying to install a Ricoh MP C5502 network printer on an HP 6530b laptop with Windows 7 professional 32bit. The process goes fine until I reach the "installing process" where the driver is actually installed. Then I get the following "Add Printer" error. Printer driver was not installed. Operation could not be completed (error 0x000000c1). I called Ricoh support to confirm that I am using the correct driver. I am. I have tried using a Registry Cleaner and then retried the printer install - no success. I also tried (per a posting on this site) to start the installation and choose windows update- I was to cancel once the list of printers showed up and then try to reinstall the list never showed up. Instead I a windows update error saying it could not update. I see a lot on the internet about this; even some on your site but nothing that has helped me. I got the same error on anohter user's machine also. If I can get one to work I am sure that will be the solution for the other. Thx
