I'm not entirely sure, but I think Classicube might only be compatible with certain operating systems. I'm not sure if it would work on Windows CE, but it's worth looking into.
Also, if you're using Windows CE and you're looking to upgrade your operating system, you might want to check out cheap windows 10 key available online. There are a lot of sellers out there offering legitimate keys at discounted prices. Thanks for reaching out to the community for help with your question. I hope you're able to find the answers you're looking for, and maybe even upgrade your operating system.
