I asked this question on your email, hope to get answer to it. Is there a support for win xp? I get that weird error not valid win32 application. I updated to 4.0 netframework but notthing..
I tried responding to your email but my phones internet wasn't working properly, so here's what i tried to say:
There is no version that supports xp. To compile one that does support xp you will need to set the project target framework to a version of .net that xp supports (4.0 is the latest vs supported by xp I think) and remove or change all functionality that requires .net 4.5. You can try compiling some older commit that depends less on .net 4.5.
Or just update your windows. Xp has reached end of life long ago, you're putting yourself at risk by using such an old OS.
