A: No. The license is perpetual for the version you download during your active maintenance period. Only the maintenance (right to updates) expires annually.

Q: My code is obfuscated. Will that affect UnlockBundle?
A: No. Obfuscation does not interfere with the string-based license check. However, ensure the string is not altered or encrypted before passing it to Chilkat.

Q: Can I sell software that includes Chilkat components?
A: Only with an OEM/Redistribution license. A standard Developer License does not permit redistribution of Chilkat DLLs to third parties.

Q: How do I verify that my license is already unlocked?
A: Call the glob.IsUnlocked() method after UnlockBundle. It returns true if the key was valid.
