Finally! I found a solution that worked for the Nvidia error code 28. During installation I kept getting an error (both Nvidia installer and Windows Update). Tried to remove all references to the Nvidia driver but nothing worked. Did safe mode, cleaning registry, etc. But nothing seamed to fix the “code 28” error.
Until I lanched the “sfc /scannow” (more on the System File Checker tool in the Use the System File Checker tool to repair missing or corrupted system files). But after running sfc and it fixed so system files the Nvidia driver installation was again running like a life through butter 🙂
Problem solved! (I did this fix on Win10 build 10074).
