For your cutting edge pleasure, I offer a new version of Synfig for Windows…
Old style - still need GTK, GTKmm, but compiled with GTK 2.16, so you may need to update if you’re still running GTK 2.10. (Thanks to Zelgadis for helping me update)
synfig.org/files/synfig-0.61.09_ … master.exe (7MB)
synfig.org/files/synfigstudio-0. … master.exe (4.5MB)
****** OR ********
Shiny new all in one installer!!! Uninstall GTK, GTKmm, and just install this one!
P.S. the all in one version has SVG support. I think I forgot to fix it for the old style.
You still need to restrict Synfig Studio to only one CPU/Core.
