Just a note on this: The Filemaker Go version prior to Go 12 could also run fp7 files.
Go 12 only runs Filemaker 12 files so you will have to convert your previous Filemaker Pro files to 12.
Go 1.x only runs Filemaker files with the .fp7 suffix and will not run .fmp12 files.
Go 12 is currently free and hopefully free forever which makes it a "free runtime" that people were asking for.
The point I was making is that now other people who want to run your files can download Go 12 for free and do so, hence 'free runtime'.
I wonder how long Filemaker will offer the free Go 12?
Jack, my appologies, excellent points.
