Installing FMS 18 / Uninstall Filemaker 15

[mvoogt]

I have a macmini running Catalina. I'm trying to uninstall Filemaker Server 15 so that I can install Filemaker Server 18. However the 15 uninstaller does not work on Catalina. Is there another way to uninstall FMS 15?

Use the uninstaller application located in the /Library/FileMaker Server folder.

And after you do, rename the leftover /Library/FileMaker Server folder, reboot the server and only then install FMS18.

You don't want FMS18 to re-use some of the leftover files that the uninstaller won't remove.

My issue is that I'm already on Catalina and the FMS15 uninstaller app doesn't work on Catalina. Should I just delete the /Library/FileMaker Server folder?

At this point I would wipe the system and install Catalina from scratch.  If your machine is dedicated to FMS that shouldn't be too much o a hardship.
