Already solved the issue. Mpk is in reality a projectpackage so: - download the package. - (rename to .zip and) extract the package - start the project.mpr - Select the recaptcha module - export the module to a module package - close project - import this module package to the desired application
Must be something with the config of the mpk file, but if you first import the mpk from the app store and get the error and then import the module manually by using the import module from the context menu in the project explorer the module will import into your project. Not sure if it will function correctly, but at least this will get you one step further.
And please file a support ticket for the module from the app store so it can be fixed for future use.
