Due to changes of the installation path, you need to manually uninstall the old version of Glue before running the new installer. Otherwise, you will end up with two Glue installations, which will cause problems.
You're currently trying to download a build of the beta release channel. We do not recommend using beta versions in production because they may contain bugs and may not be stable.
Due to changes of the color format, you cannot go back to a stable version after opening solutions with this beta version. Therefore, we strongly recommend that you backup your data folder before installing this beta version!
To make a backup, you can either export all your solutions via the UI or copy the glue directory (on Windows it's
C:\Users\YOUR_USERNAME\AppData\Roaming\MakePro\glue\solutions, on MacOS it's
/Users/YOUR_USERNAME/Library/Application Support/MakePro/glue/solutions). If you want to restore your data, you can either import the solutions you exported or copy the backup back to the glue directory.
