MacOS Catalina install problems

[Appius]

I just did the install on MacOS via the instructions here: viewtopic.php?f=44&t=125120#p1546742

Things went more or less according to the instructions, with a couple of exceptions. One is that the AMV installer gave me two options. I used the AMVpack_200720_x86.exe versions. Then the system complained that it couldn't run that file (the new Gatekeeper functionality) after I selected it during the install, but when I hit "cancel" it seemed to complete the install anyway.

The other difference is that the UT component is not called "utvideo.component", but "utv_qt.component". Not sure that makes a difference.

Of the four apps that I made shortcuts for, the last two (DGIndex and VirtualDub) seem to run ok when launched. AvsPmod complains about not being able to find the dll's, even though they seem to be in the directory there: "[Error 126] file not found" and gives me the option of locating the dll's, but just returns to this error. I notice that the error talks about avisynth.dll but the actual file has different capitalization: AviSynth.dll. (It doesn't make a difference if I change the name to have all lowercase.)

Here's that path: /Users/username/Library/PlayOnMac/wineprefix/AMVpack/drive_c/windows/syswow64/AviSynth.dll

AMVtool crashes. I can share the log.

Finally in the config screen, my wine version says just "System". No choice to pick something with a version number.
