Crusader56, I can't answer your PM as your inbox is full. You need to delete some old messages!
So, the answer:
G'Day Noel.
Another Melbournite. Excellent.
Have you had a read of this thread, and the threads linked in it?
https://yabb.jriver.com/interact/index.php/topic,115494.0.htmlSpecifically, if you are getting the error message "your license file is for a different product", then check for the issue in this post:
https://yabb.jriver.com/interact/index.php/topic,114872.msg794447.html#msg794447It may not be the issue you have, but the first thread above and the pages it links to covers a bunch of issues. The most important are;
1. You need to download MC24 and install it before double-clicking the mjr licence key file. Install MC24 first, then apply the licence file. Download from here:
https://yabb.jriver.com/interact/index.php/topic,115332.0.html2. You should have received an email from buy-button with the mjr Licence Key file attached. If that was recent you don't need to do a Restore Licence.
3. If you restored MC24 more than 14 days ago, the mjr file will have expired, so you will need to do a Restore Licence. Make sure you use the Registration Code from MC24 buy-button email when doing a Restore Licence, so that you receive a new MC24 Install Key. Always
copy and paste the Registration Code from the email you received when you bought the MC24 upgrade. It is too easy to miskey the code if typing it.
4. Check to see if the correct PacakageInstaller.exe is being called when you double click on your new mjr file (Install Key), as per my post in the second link above.
It probably wouldn't help to uninstall MC23.0.104 before installing or trying to licence MC24.
Sorry there is no quick fix. It isn't complicated, but you need to follow the instructions carefully, and read the pages on the topic so you understand what MC is doing.
