You can install ChemPlugin SDK under Windows 11 or 10. The vast majority of users should install the 64 bit, rather than the 32 bit version.

You should have a current model Intel x86-compatible processor, at least 16–64 GB of memory, and 300 MB of available disk space. The SDK is capable of multithreading, in which case it works best with eight or more computing cores.
