@3com-I've never used 2015 with the GG source code, always used 2017 but works well in 2017. I'm actually installing vs2019 on my new laptop to see if it works with that version. So not sure what XP incompatibilities there are, so not sure I can help. XP is pretty much defunct and unsafe to use these days, but still one of my favourite Windows OS versions.
