## PeerBlock Plus Portable Issues

The built in updater uses the Windows integrated internet components to connect and download the daily updates to the blocklist. Windows must be properly configured within Internet Options inside Settings for these to function correctly. If you experience issues with updates, you can run PeerBlockPortablePlusUpdater.exe directly inside PeerBlockPortable\App\Updater to run it in debug mode. It will create a message box with the details of where it is downloading from, to, and any http responses returned. Please note that PortableApps.com can not assist with getting the built in Windows internet components to function.
