SetupCopyOEMInf windows 7

From: Phil on 16 Mar 2010 05:22 Hi I am facing a similar problem using DevCon to force update of driver I currently have under development. Worked fine in XP but with Win7 the old driver is reinstalled. Have tracked it down to the SetupCopyOEMInf that is executed as the installer processes the inf file. In my case what happens is that it sees that it already has an 'OEM Package' for the driver in ...system32\DriverStore\FileRepository\<my_driver_name>.. and kindly saves time with the message: 'Package already in store: Skipping Driver Store Add' I see the above in the file %windir%\inf\setupapi.dev.log My guess is that down at the execution level your problem is the same although you are invoking the call via a more direct route. I have two workrounds: a. Uninstall the existing driver and check the box to delete driver files. Then do your install. b. use 'devcon dp_enum' to see the list of oem packages in the driver store. Id which is yours eg 'oem1.inf' Then use devcon to remove it from the store ie: 'devcon dp_delete oem1.inf' I am still looking for a better soloution. If someone already has one please share.

My program work in XP and Vista , in Windows 7 when I plug the printer the sistem search the printerdriver using the Windows Update procedure , and only after skipped this phase, install the printerdriver using my pre-installaed signed files ( inf, dll, etc, ) . Why ? Thanks for your support.

From: Mike [MSFT] on 19 Mar 2010 20:35 By default PnP will always search Windows Update to verify it is installing the latest driver that is available. User's can configure this to just use what's available locally if they want. Normally PnP would make sure that Windows Update actually has a better driver before downloading it. For printers this check doesn't work and so PnP will always download the printer driver from WU even if there is a better one locally already. However it should still install the driver with the better rank between what is local and on Windows Update. -Mike "steven6464" <steven(a)fastweb.it> wrote in message news:AFD12E2F-EBF2-46FC-BA03-568420EC4FB1(a)microsoft.com... > Hi, > I'm using the SetupCopyOEMInf API to pre-install a USB plug&play printer. > My program work in XP and Vista , in Windows 7 when I plug the printer the > sistem search the printerdriver using the Windows Update procedure , and > only > after skipped this phase, install the printerdriver using my > pre-installaed > signed files ( inf, dll, etc, ) . > Why ? > Thanks for your support. > Steven
From: Mike [MSFT] on 19 Mar 2010 20:41 Your problem sounds different than Steven's. It sounds like you are updating the driver binary but not the INF and so SetupCopyOEMInf can't tell that the driver is different than what it already has. Since you are developing the driver you how two options: 1) Just overwrite the driver binary in system32\drivers and don't worry about running through install again. 2) Uninstall the driver from the driver store and reinstall it. You can use devcon like below or you can use pnputil which is an inbox utility. The analogous commands in pnputil are: "pnputil -e" and "pnputil -d oemx.inf". 2b) Uninstall the driver with Device Manager as you indicated in a. below. When you are done developing the driver changes you'll want to update your INF to have a new version number and date. This will ensure that the driver store doesn't confuse the driver with what it already has. -Mike "Phil McHugh" wrote in message news:201031652245phil.mchugh(a)agfa.com... > > Hi I am facing a similar problem using DevCon to force update of driver I > currently have under development.
