PCIe 6536 driver

Hi all,

I was asked to update the computer with Windows 10 updates, which I did. I was then informed that the card does not work. I cannot find the drivers to reinstall, I have downloaded the firmware

but get an error when trying to install this. I have never dealt with a card like this so do not really know what is going on.

Error message:

Any help gratefully received.

Thanks all.
