AVR ISP500-ISO driver and Windows 10

[mkossmann]

I did download the driver from https://www.olimex.com/Products/AVR/Programmers/AVR-ISP500-ISO/,
unpacked it to C:/temp and tried to use Windows Device manager to install it .

It finally fails with stating that it found a driver for the device but can not install it
because a hash value for a file in the catalog file is missing. 
Any ideas how to fix that problem ?

Did you temporarily disable the automatic driver signature enforcement before trying to install the driver?

What Windows are you using?
