Tried both and failed. The Gemplus driver did not install.
As said Windows kept installing the WUDF driver.
The GCR2 USB programmer failed to work in Windows 7 and 10!
Maybe the autoinstall only works if there is an online internet connection?
But neither do the given Gemplus drivers install offline!
And Windows needs .inf complete driver files to be able to add it to the system.
My Windows 10 Pro version does not work with the given driver and both Windows 7 and 10 state that the programmer is not working.
And I can't find the exact driver files as mentioned in the PDF instruction file.
