Error code in GP: Error( 126): Driver is not installed, reinstall it now!

Not applicable

Does anyone know why a Global Protect user would receive this error message?  I have three users showing this error and I cannot seem to find out why.  I had them uninstall and reinstall the GP app, making sure they had sufficient admin rights, and they are still getting the same error.


Thank you



Hello SIr,

Please find below procedure to open Windows registry.

  1. Click on the Start button and then click Run....
  2. In the search box, or Run window, type the following:regedit


Thank you!  The issue is the users are in China and the time difference causes a problem, so I have forwarded this to them to do.. Still waiting on a reply.

Please take your time and collect information from the end user, accordingly i will provide you the next step to proceed.


One of my team members got a response from them and just forwarded it to me: "We had an idea and guided one guy to install/config VM and it worked inside the VM.  Should be environment issue on his laptop, the VM is a clean Windows 7 and no issue arised this time.  Instructed other users to do the same but issue seems to be resolved."

Thank you for your assistance and quick responses!

Yes Sir,

You are correct, it seems like a Operating System ( OS) environmental problem but, not in the GP client, most probably the same type of interfaces that get allocated many times inside the REGISTRY KEY; in this types of situation the interface will be the culprit, and you can try to uninstall that interface to see if the problem goes away; however, if this is not the case, the user may run some registry cleanup tool which removes the interfaces from registry but the tool cannot change the NDIS bitmap key since this key is only a snapshot of NDIS cache; if this is the case, the user may need to re-install his computer to get around this NDIS bitmap corruption.

Hope this helps.
