I have recently bought and installed a permanent copy of W 7 PRO and had no problems up till installing the printers. I tested the release copy of w 7 Ultimate for 3 months w/o having any major issues so I'm quite surprised at this. Anyway I want to install a non-connected printer by picking it from the lists in the "Install Printer Wizard" but every time it tries to load the selected printer it returns a message "Printer driver
was not installed. Operation could not be completed (error 0x00000003)." I had previously installed my printers on the RC 7 copy through the wizard and as I said had nothing like this happen and exactly all the same hardware was in play. I have 2 printers on a print server so I have to install the printers first so I can config them in the server menu. If you run the hardware discovery wizard of course it doesn't see anything new and doesn't go any further than the searching stage so I cancel out of it. I'm just a little stunned to see something like this after having a great experience with the release copy!
