Have been using Mad 6.9 with no issues... today, it won't open. Running Windows 11. Attached is screenshots from event viewer. Mad5.7 opens fine??

I tried uninstalling / reinstalling Madmapper, Microsoft Visual C++ 2013, latest window updates.... nothing is working. Show starts in 10hrs and my backup PC is a piece of shit.

Sorry I have not seen your post before. Did you find a solution. Best is to have a log file so we can see where MadMapper was in its startup. Certainly related to graphics drivers, or some camera / audio drivers installed.
Let us know your findings
