The latest .Net framework will work fine. The latest has the older stuff built into it that's needed for the application.
There are no issues Basemapz. This is a standalone application that creates a route in a folder. You then import that route into TRS19 through Content Manager. Dragging and dropping the route on to Content Manager works fine.
I do recommend setting up a separate export location than the default C:/users/your username/app data/local/N3V Games/TRS19/Build xxxxxx/edit. In my setup, I placed the exported routes in a temporary folder. i.e., E:/temp because I wanted to keep the folder for future use.
Be sure to check the KUID range as well. You don't want to overwrite one of your own routes or other content you may have created. Check in Content Manager by sorting by KUID on "My Content". You can set the starting range for these exported routes in Basemapz.
When you set the size of the routes, you may need to make them a little bigger than you think if there are isles between parts of the layouts. When exporting, with the measured dimensions, I have found the isle ways to be a bit too narrow for a human to stand in.
