Chevie on Windows

I am currently trying to install SageMath and gap3 (because I am in need of the Chevie package) on my Windows 7 computer. I am using Jean Michels gap3 for this, which I found at his website. So I unpacked it to where my sage files are and tried "gap3 = Gap3(command='/usr/user/.sage/gap3-jm/bin/gap3.cmd')" , because it says on the doc.sagemath site that this will lead sage to the version of gap3 that I want to use (it says in the ReadMe that the cmd file is the one for Windows). But if I type in "gap3" in sage afterwards gap3 doesnt open and if I try something like "x=gap3(1+1)" sage just tells me, that I didn't install gap3 the right way.

I am not able to provide links because of the Karma system, but I hope that it became clear what sites I am referring to. I would be very happy if anyone could provide a fix to this.

I don't think gap3 has been tested much with Sage in a while, much less on Windows. I would be surprised if this worked at all. Could you please enumerate the exact steps you tried (like, the actual commands)?

Thank you for your reply. I downloaded Sage for Windows and installed it (Sage itsself is running completely fine). Then I went to Jean Michels website and downloaded the file gap3-jm11mar19.tar.gz . After that I altered the gap.cmd (that includes date about gaps location and such things) and opened sage. Here I tried to teach it the location of gap3 by using the line gap3 = Gap3(command='/usr/user/.sage/gap3-jm/bin/gap3.cmd') If I run the gap.cmd by itsself I get the usual gap3 opening screen, but Sage somehow refuses to let me calculate stuff with it. I tried stuff like gap3('1+1') or Gap3('1+1'), but it didnt work. So I didn´t do that much until now and so I am not able to see where it could have went wrong.

@Erratis Respectfully, that doesn't really add anything that wasn't already in your question. I meant the exact steps. Like, line by line, the commands you ran at the command line (not to mention how you "altered gap.cmd"). Otherwise I'm not sure I can easily track down the issue. When you say "it didn't work" what happens that you didn't expect?

Actually, belay that. I tried to get it to work myself and it turns out this will be non-trivial; perhaps not worth the difficulty.

I will take away from this that I just shouldn´t try making it work as an amateur. I will just go ahead and install Linux then, because I have a glimmer of hope left that it might work there. Thank you for your efforts!
