Problem 

I have "strange" error messages when I try to install the drivers (or a strange unexpected behavoiur). This is usually caused by mix of old and new drivers and now I would like to delete all my KVASER drivers from my computer and reinstall all the drivers again. 

 

Answer

Before you start this uninstallation of the drivers 

Remove / Unplug / Eject all KVASER hardware from the computer!

 

1. Begin UNINSTALLING the driver using our cleanup-programs. Click here for detailed instructions. 

2. When the computer has re-started open the "Search" program in Windows. 
(Click "Start" -> "Search" -> "For files or folders"). The following window will pop up:

3. Type "kvaser" in the "Containing text:" (see point 1 in figure above)  field. Setup the 
"Look in:" (see point 2 in figure above) directory to "C:\WINNT\inf". WinXP user should serach in "C:\WINDOWS\inf".

4. Click "Search Now". When the search is finished you will see a list (see point 3 in figure above).

5. Open the Explorer and browse into the "C:\WINNT\inf" (see point 2 in figure below). 
This is a hidden file, if you can't see it (like in the figure below) click "Tools -> Folder Options". 
In the folder options you select view and under "Files and folders"/"Show hidden files" radio button.  

6. Delete the files that was displayed in the "search result list" in point 4 of this document. 
In this example the string "kvaser" was found in "oem0.inf" and therefore oem0.inf and 
corresponding oem0.PNF should be deleted.


  REMEMBER TO DELETE BOTH THE oemXX.INF AND CORRESPONDING oemXX.PNF

Example: You find the string "kvaser" in oem12.inf => delete oem12.inf  and oem12.pnf

 

7. If you don't have installation of a CANcardX of this machine you may do the same 
procedure again but search for the string "cancardx" instead of "kvaser" in point 3 of this document. 

8. When all this has been done try to install the drivers again, click here for instructions.

Still problems? 

Even if your user account on your computer says that you have ADMINISTRATOR rights it is possible for your system administrators to disable the function to install DIGITALLY UN-SIGNED MICROSOFT DRIVERS. (=You are only allowed to install digitally signed drivers (they are signed by Microsoft). Since KVASER's drivers are *not* digitally signed they will not be properly installed).

Browse to your WINNT\WINDOWS directory (usually "c:\WINNT\", "c:\WINDOWS\") and there you will find a file called "setupapi.log". Search for "KVASER" (in this text file) and you will see what went wrong during installation of the hardware.

Talk to your system administrator to give you full rights if that is the problem!

If you still heave questions don't hesitate to contact support@kvaser.com.
