Hi Steve,

Thanks for providing all of that, it's greatly appreciated.

I followed each of your directions but at the: "cat /etc/os-release" there was something like "nothing found" or "no file"...
Figured "that" response might've been correct so continued on following your directions.
Each following command did run & supposedly got to the end requiring the [Y/n] entry, to which I did "Y".
That was it for Terminal, nothing more happend...

At this point with my previous attempts, the Application Menu now had the "Wine" sub-menu.
In the last of those attempts, I needed to restart to get the sub-menu to populate with the "winecfg"

Following your directions, this time there was NO "Wine" sub-menu..?
Using the past experience, I rebooted & still no "Wine" sub-menu...
Did a Terminal command: dpkg --list *wine* ,resulting in: dpkg-query: no packages found matching

So at this point I appear to have done everything "by the book" yet it's failed to provide me with any results.
I might go back the the "Flatpak" install which at least gave me a full Wine 9 install & try installing MoI V4 again.

HTH, Colin
