I've made a little discovery today, and thought it might be of interest
The original author of MSTS Activity Analysis retired more than 3 years ago, but a certain Karsten Pohl was given permission to publish the program and its registration key. He is also maintaining German Railroads after their closure.
The program and key are available here : https://forum.german-railroads.de/index ... dataID=753
Note that this site describes the software as v2.19, but it appears to be v2.18; the registration details work correctly for both versions.
The software and registration details are also included on the "10 Jahre virtuelle Eisenbahn" (10 Years Virtual Railways) DVD.
I appreciate there was a thread with a similar title to this a few years ago, but as I wasn't the original poster, was uncertain if I could request its re-opening : http://forums.uktrainsim.com/viewtopic. ... s#p1528268
Reading that original thread, I note that there were some comments about it not working for mini-routes. May I give advance notice that a new utility I have under testing WILL allow Activity Analysis (along with a few other utilities) to be used with any MSTS (or, even, ORTS) installation.
Cheers,
Ged
