Problem with Activation due to significant changes of the PC or integrity fault of the Activation Key

If you have this message: The Activation Key is not valid any more due to significant changes of the computer Hardware configuration (Invalid Hardware Code), or Unable to run the application due to integrity fault of the Activation Key.

Also the error can appear in different instances and not just hardware changes. For example, in case of the common DCS World update with MiG-21 module 

These reg files can help you if you did an upgrade of PC without correct procedure of de-activation of the serial number and all other instances of this error.

You should use it whenever you have an issue with activation.

You have to download reg file for affected module   (you can use Save Link As ... option).
Please run the reg file it will delete old (wrong) information about activation from your Windows registry.
Then please try to activate your product again.

Registry fixes for modules:

Registry fixes for campaigns:

If for some reason reg file doesn't fix the activation problem, you need to delete the wrong entry manually

Here is an example for MiG-21 keys:

run Regedit command and manually delete all the entries under the DCS:MIG-21Bis\Keys node.

Please find the entry not only under hkey_local_machine but also under current_user subtree too. 

You have to delete the Keys node manually from BOTH subtrees:

HKEY_LOCAL_MACHINE\SOFTWARE\Leatherneck Simulations\DCS:MIG-21Bis
HKEY_CURRENT_USER\SOFTWARE\Leatherneck Simulations\DCS:MIG-21Bis
