From what I gather from FPM:

This is caused by the a package you already have installed.
I can make an exception in the package but that seem rather specific for your use case.

sudo pacman -Rns renamemytvseries-qt-bin

Should fix it ... just unsure why it would think its the same thing (probably the fact that the binaries for GTK and QT are having the same name - something I should fix).

I could (should) also remove ffmpeg and ffprobe from the package and add it as a dependency.
That should fix this error:

RenameMyTVSeries: /usr/bin/ffmpeg exists in filesystem (owned by ffmpeg)
RenameMyTVSeries: /usr/bin/ffprobe exists in filesystem (owned by ffmpeg)

Just wondering, should I rename the binaries with a version number in it?
Eg. RenameMyTVSeries-2.3.16-GTK and RenameMyTVSeries-2.3.16-QT5

Would this cause problems in the future?
Or should I name them like so:
RenameMyTVSeries-GTK and RenameMyTVSeries-QT5

Edit: never mind, figured it out (stick to renamemytvseries as a binary filename).

Why remove those from the package when you simply could include a install note in what I sent you after purging my settings and just have peeps extract it and put it where they want it? I removed the AUR version, but still getting that message. As for renaming honestly you'd probably know best.

Haha, I appreciate your optimism 😉 
Well, done some searching and I figured out the naming.

My goal is to make an easy to install package by most Linux users.
So with some effort I think I figured out how this should work for deb and pacman packages.
Sounds like those are most common (Debian based and Arch based distros seem most common).
As far as I understand, most peeps just use the package manager and don't think any further of it.

Removing them (ffmpeg and ffprobe) from the package makes them a lot smaller (less than 2.5 Mb) which could be seen as an advantage, and one wouldn't have potential duplicate installed ffmpeg and ffprobe. The package manager will handle the ffmpeg dependency automatically (they say).

After removing the AUR version, does the desktop file and binary still exist on your system?

On another note: tested the Qt5 version and it's really terrible - will do some digging into the code to see if I can force a refresh so the controls are visible.
Maybe later today I'll post new versions (read: packages).

Since I extracted the older to my downloads and created the desktop shortcut to run it from yes the files still exist. I did have to redo all my settings though. Other than the one error message in the above image all looks good. I can't really test for you right now cause I'm in the secondary OS and have very little installed right now. Once I'm

back in my main OS I'll backup my current folder again, uninstall that version, make sure there is no folder left under my user, then install your new version, set it up for my needs, and test it with whatever new files I get today. Probably be sometime tomorrow before I can report cause I have someone behind the scenes doing some custom work on the system, so I can boot into my main OS til they're done for the day.

I removed the previously created 2 packages and replaced them with these.

Debian GTK3 version deb file

Pacman GTK3 version

Debian QT5 version deb file

Pacman QT5 version

I managed to fix the Qt5 issue, seemed Wayland related.

These "should" be properly packaged according to the documentation I could find.
You'll notice them being a lot smaller than before.

Of course, as long as the AUR version (I know, you did an uninstall) somehow has its binary and .desktop file on your system, these may not work.
Would be nice to know if and why its still there. (I never maintained the AUR version, and I wildly assume either the DEB or Pacman package should work)

I know, it's not a copy of your example, but I am working under the assumption that most folks would use a package installer anyway. 😊 

The main remaining issue is having a .desktop file auto-created to launch from the apps menu where one can drag a copy of it to wherever they want it. Let me go through and remove EVERYTHING I can find and install you QT5 version.

With the gtk3 version it's running. Got a old database error building a new one, but it launched. I'll set it up and let you know what I get.

OK even though I'm in the new OS I was able to test with two recent files that I had issues with and had to uncheck metadata to get them to rename. I just manually renamed them, dragged them to RMTV and they renamed without issue. Now I just need for the new files to me moved to my location of choice. No of thos seem to offer me that option.

This is what I have in the previous version.
