QT 6.7

Is it possible to install this on box64? I got a ton of errors trying to compile it.

Qt is a library, not a program: box64 cannot help with using/installing a native Qt 6. However, if you find an x86_64 program using Qt 6, then box64 can be used to run that program (note that you will likely need the x64 version of the library as well since it is not yet wrapped in box64).
If I have misunderstood your question, please clarify what "install on box64" means (I interpreted this as "using box64 to have a native version of the library using a downloaded x86_64 version").
