Still having major issues with opening Builder on a Windows 10 computer. None of the stated solutions stated previously work, including deinstalling/reinstalling both the program and Java, attempting to launch from the .JAR file, etc. What else, if anything, can I try? I am trying to hunt down an older computer with Windows 7 or earlier, to see if I can run it on that, as a last resort. This is a useful program - I would happily pay for it if it worked.
