You can run the installer without deleting files or uninstalling a previous version of the Spine launcher.

I did run the installer at first (Windows 10) without going to Win' settings and uninstalling anything. The installer is '3.7.81', however, after it ran it I opened Spine and the old one came up 3.6.x and didn't ask for an activation code, just ran as usual. So then I uninstalled the old one, reran the latest installer again and this time it started downloading files, installed 3.7.83 which runs fine as the new one. I should mention I didn't stop the first install at anytime, wasn't using any other program and just let it do its thing till it finished. I don't know, maybe it's just me and what happened, a glitch in the Matrix. Anyhoo, many thanks for all your hard work. Appreciated, I think it's great.

..redownload the installer. Launch it and it will update your Spine installation to the latest version!

Thanks as I was wondering the same. Just one thing though and maybe I noobed out as ended up still being 3.6.53 : / even though the installer was the latest one (or maybe just a 'generic' installer?) it didn't seem to overwrite/delete/download/or add new files per se as it was re/installing files when running if already there in the Windows program folder. I think it just saw that an installation was already in the program (x86) folder so didn't download the new files perhaps. If anyone has the same issue it was just a simple delete old program first as usual and then run the installer, this time it downloads files from the site and 3.7.83 comes up when Spine runs, just have to place back the original activation code when requested.
