A staff member uploaded the Ricoh Aficio MP C4000/C5000 Windows 7 x64 driver. He downloaded the driver from Ricoh's support site. The driver uploaded fine to the driver store, however, to weird drivers also loaded. They look something like this: .1.6780.0{89A5F34E-CDF3-47F4-BDA9-......etc. I was able to delete the Ricoh driver, but am unable to delete these 2 weird entries. When i delete and apply the changes, this is the error I am getting:

Exception saving drivers configuration
Request (SERVER_ERROR) - bad status code (0x505)
IPP Error: 0x505

Anyone have any ideas? We do not use Windows 7 campus wide so this was just for testing purposes at this point.
