Tested on Mathcad Prime 11.0.0.0

Ptc.License.Plpf.dll - adds RDP support (needs a valid license)
Ptc.Core.dll - is the complete crack to have commerical license

these two files do not depend on each other, as they offer different changes

Notes:
Just messing around with PTC's protections for fun and curiosity.
I've got my own legit license for Mathcad Prime, so this was purely experimental.
Not encouraging anyone to use it wrong, and I'm not responsible if you do.
Play at your own risk!
