Hi fellow simmers. I had been struggling with the VCRUNTIME.DLL CTDs for a while. Finally did some digging and found that there were several installations of Microsoft Visual C++ XXXX-XXX Redistributable (x64) packages installed on my system. Like 8 or 9. I finally ended up deleting all of them and reinstalling the latest from the x64 link here https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0.
I have now about 20 hours of flying since the changes and no CTDs so far.
Remember that some of the programs you install will also “optionally” try to install a specific VB version because that is what they used to compile the program in. So, you end up with a ton of different versions of VB installed. I know that some of the 3rd party flight sim companion apps that I have installed do this. So, going forward, I will make sure that there is only the latest installed. If the 3rd party app stops working, then so be it. I would rather fly than troubleshoot other programmers’ problems.
Hope this helps!
