I might have missed the memo.
When I build Mac and Windows versions of an app on my Mac (I have full license), I move the .exe/libs/resources over to my Windows machine and attempt to run the .exe there. I get an error, saying essentially “Can’t find XojoGUIFramework64.dll”. I looked and for some reason Xojo isn’t copying that file into the Libs folder. There is GUIKitx64.dll, but not XojoGUIFramework64.dll.
