Just saw this post in the FAQs, will try this now … > [@FAQ - MSFS Cannot Read Property “Files” of undefined](https://forum.navigraph.com/t/faq-cannot-read-property-files-of-undefined/627): > > If you should receive the message Cannot Read Property “Files” of undefined, you are likely running or have installed over an older Beta installer. Please use Windows 10 to uninstall Navigraph 1.0.xxxx Beta yyy , then re-install from [Navigraph Navdata Update Beta](https://forum.navigraph.com/t/navigraph-navdata-update-beta/133) Cheers Ian ---
