Welcome Could you see if starting the app as administrator (with explorer right click on smartdvb.exe and select 'run as adminstrator') does not generate these errors. Did you install in program files or using the local appliccation path? Installation at the local app path is the default install option. Please send me your smartdvb.log at smartdvb @ smartdvb.net (remove the spaces) if your problems persist. Program files installation requires administrator rights to write/create files in the program files folder (app data installation does not require this) . But the installation should force smartdvb.exe to run elevated with admin rights so this should really not happen.
