Possible solve of error: "Main script execution failed" First of all, why possible? Because I might have found the way. Go to the update list. Select only one application, and when hitting update. It asks some options. Hit clear queue list. Then update the app. The app updates. If it does not, it gives a problem/error (incorrect firmware because you have a older firmware). This error is not reconized in the installer 'update all'-option. Want to use the "update-all"-option? Uninstall the apps giving the errors in the Update menu. Install the latest firmware (not tested!) Known applications wich gives the error from a firmware 1.1.1 while updating: Make It Mine iPhysics Did not searched for a thread started as a provided solution for this error. Did not searched advanced for the right forum.
