Hello all, I've just purchased the Oxford - Bicester addon for the Chiltern Mainline London - Birmingham route. I got up to the installation part but it says its unable to find an installation of Western Mainlines in that location. Does anyone who knows how to install JT content know what to do because I am confused. Thanks
According to the blurb for Oxford-Bicester add-on you need the Western Mainlines route: https://www.justtrains.net/product/western-mainlines. The error message implies that you do not have that route, sorry.
As DIFFLOCK said, it seems what you purchased was an extension, thus the base route is required. If you have an extra $42 USD, then it seems like a worthwhile purchase (300 miles sounds amazing).
