Technical Document #114

In order to distribute your KernelDriver based driver to a target Windows machine (which does not have the KernelDriver software installed), when using version 5.1.x of KernelDriver (which supports the USB bus on Windows NT 4.0), follow the instructions below:

• Copy windrvr.sys, wdusbd.sys and your own SYS/VxD kernel driver — my_kd.sys/vxd — to the target computer's drivers directory — WINNT\system32\drivers.
  When copying the files, take care not to overwrite a newer version of the file with an older one.

  windrvr.sys is found under the KernelDriver\redist\register directory on the development machine (registered driver). wdusbd.sys is found under the KernelDriver\redist directory.



• Copy wdreg.exe from the KernelDriver\util directory on the development machine to the target machine.


• Uninstall the existing driver for the device (if such a driver exists).
  If the existing driver was developed with WinDriver/KernelDriver:
  1. If the driver was developed with KernelDriver or using WinDriver's Kernel PlugIn feature, first stop and delete the kernel driver service using wdreg.exe:
         wdreg.exe -name <driver name> remove
  
  
  2. Remove the current windrvr.sys and wdusbd.sys services using wdreg.exe:
         wdreg.exe -name wdusbd remove
    wdreg.exe remove
     
  
  
• Install windrvr.sys using wdreg.exe by running
      wdreg.exe install


• Install wdusbd.sys using wdreg.exe by running
      wdreg.exe -name wdusbd install


• Install your own kernel driver — my_kd.sys — using wdreg.exe:
      wdreg.exe -name <my_kd> install
  
  NOTES:
  
  1. Specify the driver name without the *.sys extension.
     
  2. You must first install windrvr.sys and wdusbd.sys before attempting to install your own kernel driver.
     
• Copy your user mode executable/DLL file (if you have created one) to the directory of you choice on the target machine and run it.
