Sounds like you double clicked .qar file and installed extensions which is why you see the Qlik Geo maps on your qvw web view but missed running the GeoAnalyticsSetup / adding - activating serial number.
If you want to redo, Please follow installation steps below (provided by qlik) and this should fix invalid key issue
"Installation: 1) Start by unzipping 'GeoAnalyticsForQlikViewDesktop-<version>.zip' into any folder on the server computer. 2) Double click the .qar files to install the extensions. 3) Run the GeoAnalyticsSetup to set up GeoAnalytics. This includes activating the Serial Number.
That is it, you should now be ready to use GeoAnalytics for Qlik View Desktop.
Remember that you have to be in webview to be able to use the extensions."
