Unfortunately the installer destroyed my NVidia display driver (replaced it with something which is not compatible with my Windows 10 PC). I was very disappointed because I was expecting something much better from NVidia. But after some investigation I have downloaded a new driver, installed it and then everything was OK (I however lost several GB’s of SSD space on my Windows drive).
I think you better tell your team who is responsible for this that this problem should be investigated and avoided at all costs. I would advice you to completely remove the display driver installation from the package and let the user know to install the last version of the display driver manually. The download will also be at least 0.5 GB less I think.
Furthermore, there are already for several years problems with NVidia installation files which unnecessarily use up a lot of HD space. Nowadays with small SSD Windows drives this is a disaster. I do not understand why NVidia does not do anything to solve this problem. I have found 10 NVidia display drivers on my system and several temporary installation directories with several GB’s of data on several places. Old drivers are not being uninstalled and it is not that easy to remove them from the driverstore.
