I have Mp3tag v3.11 (32 bit) currently installed. I see there is a much newer version, and I was thinking I should take the opportunity to install the 64 bit version. It seems I have to uninstall the old version to install a 64 bit version though.
If I do this, will it still keep all my settings/configuration/scripts, etc, in my AppData/Roaming folder, or do I need to back anything up?
Is it any less painful if I install the latest 32 bit version first?
Note I have done a "Save Configuration", but I'm wondering whether this includes everything, and what I will need to do, if anything to restore this in a new installation.

> I've released a [64-bit version of Mp3tag](https://community.mp3tag.de/t/455) a few days ago and received a few questions about differences between the 32-bit version and the 64-bit version. To make it short, there should not be any noticeable differences except for two things: The 64-bit version uses 64-bits to address memory and is no longer limited to 2 GB per application. While the [Library](https://docs.mp3tag.de/customization/options/library) feature of Mp3tag is already a very viable solution for large libraries, loosening the memory restriction is one of the key benefits of …

Thanks for pointing that thread out.
So I went ahead and uninstalled the existing mp3tag 32bit version. However, when I try to install the new 64bit one, it bails out complaining that there is still an mp3tag 32bit version installed in Program Files (x86).
There was an empty folder, which I have removed, but it still complains that it is installed.
It looks like there are some bits left over in the Registry that weren't uninstalled.

I deleted Software/Florian/Mp3Tag from the registry and I could then install. I think there were other things left over in the registry, such as Mp3TagShell, InProc32, but seems to be working now.
