Hello @Spacerox
Thank you for reaching out on the community and telling us about your issue. I believe that you're currently using quicken essentials. In order to get over to windows you'll have to get your file converted first on the mac side to a newer product. With the newest version of quicken you have the option to download on both windows and mac.
I would recommend giving us a call so that we're able to help guide you through the process since it's quite a lengthy one. You can get in contact with us here. I would also recommend to have quite a bit of time as it will be a quite long process.
Please let us know how it goes!
Thanks,
Quicken Francisco
