Unlock MIME problem

Aug 03 '17 at 09:10

I bought a "Chilkat 1-Developer Email License" in 2015 and have been using it successfully. This code works with no problems:

success = mailman.UnlockComponent("MyUnlockCode")

Some of the emails I have been trying to decode are now coming as *.eml files so I tried to follow the example here:

However, the following code:

Dim mime As New Chilkat.Mime
Dim success As Boolean
success = mime.UnlockComponent("Anything for 30-day trial.")

returns False for Success, regardless of whether I use my unlock code or just leave as default from the example. It recognises the MIME class with no problem.

Do I need to buy another different component to activate MIME? I can't see it in the list of products here:

Do I need to buy a bundle? If so, can I upgrade me existing licence or is it too old?


Accepted Answer

According to the class reference at the Mime class is part of the bundle. The lastErrorText should say why unlocking fails, see

Contact Chilkat at to discuss pricing to upgrade to the Bundle. Include your current unlock-code(s) in your email.


Ah, thanks very much - I will speak to Chilkatsoft to see how to upgrade if possible.

Also, I found while doing the testing you recommended that if I put in other text in the UnlockComponent method it did actually allow me a 30 day trial. The lastErrorText did give me the hint - said my code was good but for wrong product!
