Hi, we're experiencing printer driver problems on our Windows 7 x64 SP1 machines. When we try to remove different printer driver packages we receive this errors: Failed to remove driver HP Universal Printing PCL 6 (v5.2). The specified printer driver is currently in use. Failed to remove driver HP Universal Printing PCL 6. The specified printer driver is currently in use. Failed to remove package hpcu111u.inf. Driver package is in use. and Failed to remove driver Kyocera Classic Universaldriver. The specified printer driver is currently in use. Failed to remove package oemsetup.inf. Driver package is in use. We tried almost all suggested solutions we could find on the net like: - stop / start spooler - msconfig disabling all non Microsoft services - cleanspl.exe - http://social.technet.microsoft.com/Forums/en/itprovistaprinting/thread/14994b03-7549-4dcc-820c-2076402f7ee2 - logged on as every user, deleted both the printer and the driver - http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/trying-to-un-ininstall-print-driver-error-message/b478c408-6175-462d-96d0-5be56e61a7de - disabling bidirectional support - http://www.skidzopedia.com/2009/04/06/how-to-fix-cannot-remove-or-delete-network-printer-error-in-windows/ - RUNDLL32 PRINTUI.DLL,PrintUIEntry /dd /c \\machine /m "AGFA-AccuSet v52.3" /h "Intel" /v "Windows 2000" - printui /s /t2 - and probably other solutions that didn't help ... Does anyone have some other idea how to remove printer driver package? We really need this because we're experiencing some troubles with old drivers and we'd like to update them.

Hi oluka, Did you try remove the drive in Safe Mode? If it doesn't work, try to delete the printer driver from the registry. Note: Before you modify the registry, please backup it firstly. Click Start, input regedit in the search box, press ENTER. Find and delete the driver references at the following location: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Environments\Windows NT X86\Drivers\Version-1 Restart the Computer.

Hi Miya, thank you for reply. Unfortunately your suggestion didn't help :( But I found my own workaround that looked like this: 1. First we removed printer in "Devices and Printers" 2. Then we stopped print spooler 3. In registry we opened HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows x64\Print Processors\ 4. We renamed all Print Processors that were listed. Like Winprint to Winprint.old, Hpcpp107 to Hpcpp107.old, and so on ... 5. We started print spooler 6. Removed driver pack in Print Management MMC 7. Reopened registry location HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows x64\Print Processors\ 8. Renamed back all Print Processors back to Winprint.old to Winprint, Hpcpp107.old to Hpcpp107, and so on ... 9. Restart print spooler 10. Installed new printer drivers 11. Tested printing Maybe this procedure will also help someone else with similar problems :) Regards, Luka
