Hi. Thanks to OP for providing a handy reference to keep bookmarked. Currently on Fedora 42, I'm able to create the WINEPREFIX, but the process falls apart when I'm trying to install dotnetdesktop9 via winetricks. I suspect this is because Fedora dropped all 32-bit support a while ago, so now Wine must run in wow64 mode. I couldn't find anything remotely similar to my output on the Winetricks github, much less Google whenever I just paste a string verbatim.
