No, KONxiSE from xitech.
It does what this wwf-vfp wants to do... and does it w/o any external additional DLL's. Doesn't require you to change the name of your exe etc.

What will your dishonest users do? They decompile the loader applet to find the password, get Cryptor from Xitech and decrypt your app.
