Crossgrade Mac to PC

[abzr613]

Hi, I purchased the Mac version of HIARCS Chess Pro and I really don't want it for Mac. I want it for Windows. I have Chessbase on Windows and I see that I can use files from Chessbase in HIARCS. How can I either change or crossgrade my purchase from Mac to Windows?

Thanks.

You know you can put chessbase databases like the big or mega database on HIARCs Mac version. It’s not too tricky. There’s some instructions within this forum on how to do it.
