// Starting in v9.5.0.49, all Chilkat classes can be unlocked at once at the beginning of a program
// by calling UnlockBundle.  It requires a Bundle unlock code.
Chilkat.Global chilkatGlob = new Chilkat.Global();

if (success != true) {
    Debug.WriteLine(chilkatGlob.LastErrorText);

// The Chilkat PEM class was introduced in v9.5.0.49.  
// It requires the bundle to be unlocked, as shown above.
