WinDriver Uninstall Instructions

NOTES:

• For Windows 98/Me, replace references to wdreg below with wdreg16.
  
• For Windows 2000/XP/Server 2003/Vista, you can also use the wdreg_gui.exe utility instead of wdreg.exe.
  
• wdreg.exe, wdreg_gui.exe and wdreg16.exe are found under the WinDriver\util\ directory.
  

1. Close any open WinDriver applications, including DriverWizard, the DebugMonitor (wddebug_gui.exe) and any user-specific applications.

2. If you created a Kernel PlugIn driver:
   • If your Kernel PlugIn driver is currently installed, uninstall it using the wdreg utility:
     
     wdreg -name <Kernel PlugIn name>
         uninstall
     
     NOTE:
     The Kernel PlugIn name should be specified without the *.sys extension.

   • Erase your Kernel PlugIn driver from the
     %windir%\system32\drivers directory.

3. On Plug-and-Play Windows systems (Windows 98 / Me / 2000 /
   XP / Server 2003 / Vista):
   
   Uninstall all Plug-and-Play devices (USB/PCI/PCMCIA/CardBus) that have been registered with WinDriver via an INF file:
   • On Windows 2000/XP/Server 2003/Vista:
     Uninstall the device using the wdreg utility:
     wdreg -inf <path to the INF file>
         uninstall
     
     On Windows 98/Me:
     Uninstall (Remove) the device manually from the Device Manager.

   • Verify that no INF files that register your device(s) with WinDriver's kernel module (windrvr6.sys) are found in the
     %windir%\inf directory and/or %windir%\inf\other directory (Windows 98/Me).

4. Uninstall WinDriver:
   • On the development PC, on which you installed the WinDriver toolkit:
     
     Run Start | WinDriver | Uninstall, OR run the uninstall.exe utility from the WinDriver\ installation directory.
     
     The uninstall will stop and unload the WinDriver kernel module (windrvr6.sys); delete the copy of the windrvr6.inf file from the %windir%\inf\ directory (on Windows 2000/XP/Server 2003/Vista) or %windir\inf\other\ directory (on Windows 98/Me); delete WinDriver from Windows' Start menu; delete the WinDriver\ installation directory (except for files that you added to this directory); and delete the short-cut icons to the DriverWizard and Debug Monitor utilities from the Desktop.

   • On a target PC, on which you installed the WinDriver kernel module (windrvr6.sys), but not the entire WinDriver toolkit:
     
     Use the wdreg utility to stop and unload the driver:
     • On Windows 98/Me/2000/XP/Server 2003/Vista run:
       wdreg -inf <path to windrvr6.inf>
           uninstall
       
       NOTE: When running this command, windrvr6.sys should reside in the same directory as windrvr6.inf.

     • On Windows NT 4.0 (v8.02 and below) run:
       wdreg uninstall

     (On the development PC, the relevant wdreg uninstall command is executed for you by the uninstall utility.)

   NOTES:

   • If there are open handles to WinDriver when attempting to uninstall it (either using the uninstall utility or by running the wdreg uninstall command directly) - for example if there is an open WinDriver application or a connected Plug-and-Play device that has been registered to work with WinDriver via an INF file (on Windows 98/Me/2000/XP/Server 2003/Vista) - an appropriate warning message will be displayed. The message will provide you with the option to either close the open application(s) / uninstall/disconnect the relevant device(s), and Retry to uninstall the driver; or Cancel the uninstall of the driver, in which case the windrvr6.sys kernel driver will not be uninstalled. This ensures that you do not uninstall the WinDriver kernel module (windrvr6.sys) as long as it is being used.

   • You can check if the WinDriver kernel module is loaded by running the Debug Monitor utility (WinDriver\util\
     wddebug_gui.exe). When the driver is loaded the Debug Monitor log displays driver and OS information; otherwise it displays a relevant error message.
     On the development PC the uninstall command will delete this utility, therefore in order to use it after you execute the uninstallation, create a copy of wddebug_gui.exe before performing the uninstall procedure.

5. If windrvr6.sys was successfully unloaded, erase the following files (if they exist):
   
   • %windir%\system32\drivers\windrvr6.sys
   • %windir\inf\windrvr6.inf (Windows 2000/XP/Server 2003/Vista)
   • %windir%\inf\Jungowindrvr6.inf (Windows 98/Me)
   • %windir%\system32\wdapi<version>.dll for the WinDriver version that you are uninstalling (for example wdapi900.dll - for version 9.00).
     For version 7.x of WinDriver, earse the file wd_utils.dll.
   • %windir%\sysWOW64\wdapi<version>.dll for the WinDriver version that you are uninstalling (for example wdapi900.dll - for version 9.00) (Windows x64)
     

6. Reboot the computer.
