The displayed error msg suggests that your test script does not contain required #include MCFinclude.au3 (anymore). Without it, CodeCrypter cannot produce an encrypted version. If you have not edited helloworld.au3 yourself, then your files may be corrupted; delete everything and re-download the package from the official Autoit repository (various idiots have posted copies elsewhere; I cannot vouch for that content). I did test the helloworld example again just now, which can be encrypted without any issues, and runs normally.

I fixed this by using the "Compile script to .exe" tool and setting compatibility mode on the generated executable to run as Administrator. Works in Windows 7 and Windows 10.
