Blue screen on windows 11 after due to corrupted vcidrv.sys file

Dear all,
After installation of the IXXAT interface, I got blue screen on Windows 11 due to wrong digital signature of vcisrv.sys file.
Any way to solve this issue ?

Which IXXAT interface do you have? What is the firmware version?

Which version of the VCI driver do you have?

As my computer is blocked at boot due to wrong VCIDRV.sys, I am not able to say you the version of it. It is quite incredible that you release a product that is able to completely crash a computer…
So please let me know how I can solve this very difficult issue.
I am working with Windows 11.
Best regards

Please send a picture of the device label.

You can check the VCI version in Windows Programs and Features without having the USB-to-CAN device connected to the PC.

Dear Kyle,

I have a similar issue as described above. I have the VCI3.5.2.4268 driver version that blue screens a win11 pc when installing.

I have attached a photo of the usb-to-can device used.

Best regards,

Hi @MatyasP,

The VCI V3 driver is obsolete and does not support W11. It has been replaced by VCI V4 which supports W11.
