    Runtime Error! Program C:\WINDOWS\SysWow64\RunDll32.exe


    Hello. I've been trying to update my Nvidia drivers and I haven't had this problem until now (been using Windows 10 for about a month or two with many past driver updates not giving me any problems) and I keep getting this error. One solution was to do a registry cleaner, and I did that, but still got the error. Help? I don't really understand now.

    Here's the full error:

    "Microsoft Visual C++ Runtime Library


    Runtime Error!

    Program C:\WINDOWS\SysWow64\RunDll32.exe

    This application has requested the runtime to terminate it in an unusual way. Please contact the application's support team for more information."



    Also, here's the list of my PC build, if that makes a difference - AMD Athlon X4 860K, EVGA GeForce GTX 960, NZXT Source 210 (Black) - System Build - PCPartPicker

    Runtime error of rundll32.exe on Win10


    Thanks!

    I don't have the startup entries calling this. I have installed VC++ 2015 x86 and reinstalled the x64 version. Let's see if it happens again.

    By the way, the error only happens occasionly after login the system. If it happened, only 1 time.
