64-bit Daz Studio was working perfectly on my Windows 11 surface laptop with NVIDIA GeForce RTX 4050 up until today, where I keep getting this error every time I try to open Daz. Earlier this week I was getting this same error on a different program (Davinci Resolve) but I fixed it today, so that probably has something to do with it. But the thing is, I don't know what exactly fixed that program, and if it's causing conflicts with Daz I don't want to have to juggle between both. I don't want to have to uninstall and reinstall .NET framework and constantly upgrade/downgrade my graphics drivers just to switch between the two programs. Is there a way to fix this problem so I can run Daz again? Which NET library and graphics driver do I need?

    Daz was working perfectly fine on my Windows 11 until a Windows update completely screwed up my graphics driver and now I cannot launch Daz or Install Manager or anything no matter what I do. I've tried uninstalling and reinstalling and removing the 32-bit C++ redistributables but nothing works. How do I fix this??????????????

    You are using the 32 bit version? What is the error code you are getting, if any? What GPU driver are you using? Have you tried a clean install of the driver?

    I'm using the 64-bit version, the same as I always have until it stopped working. I'm only getting the generic Windows error code 0xc00007b.

    My GPU is Nvidia GeForce RTX 4050. I already had to reinstall it because of another program that stopped working, but now Daz doesn't work.

    Threads merged, please don't multi-post or bump.

    Try using a driver that is the minimum required version, or not a lot later, as lsied in the Release Highlights or Iray threads.

    I am having the same issue, reinstalled windows 11, and applied the latest windows updates, as well as the latest NVidia drivers for the 3090, but Daz wont start saying  This application was unable to start correctly (0xc000007b) click ok to close the application.

    I have tried everything listed here and am now headbutting walls.
