Server NW6.5sp8 with all the latest patches for the server and iprint. I
have no problem uploading drivers for windows 7.

OK, so I select iPrint from iManager. Select Printer Driver Profile.
Select my Print manager and select "Create Printer Driver Profile". Hit
OK. Next page, select the correct print driver. Now here is the catch,
at the top where it says "Desktop Operating System:" is blank. Create a
name for the profile, select correct driver, hit next. Shows this on the
page.

Save driver profile CM8050


Print Manager name: NDPS_Manager.NSI

Broker name: NDPS_Broker.NSI

Desktop operating system:


Hit next, then get this


Error: Create Printer Driver Profile Failure
Error occurred configuring driver.

Any ideas on what maybe causing this?
