I've just purchased the app, but I'm unable to unlock/register it.

Audio Record Wizard is now exclusively available through the Microsoft Store.

If you are currently using a trial version of Audio Record Wizard 7.21 or earlier, we kindly ask you to uninstall it. Please proceed to download and install the app directly from the Microsoft Store.

Once you have purchased the app from the Microsoft Store, there is no need for a registration code to unlock it, the app should be fully functional immediately following installation.
