ToT on Windows 11

[Ravenhawk9999]

I've followed all the patch instructions I can find, and run K-Light to make sure the codecs are active, but as soon as I get to the world building stage, ToT crashes to desktop. Same thing happens if I try to start the Midgard scenario. This system started as a windows 10 system, and I had no issue then, but since it updated to 11, I cannot play ToT. I am having the same issue on my tower, which was built as a Win 11 system. Neither system has an integrated cd-rom, but I am not getting any warnings about cd missing.

Any help?
