Hmmm...after several years of muting Simutrans, I installed 1.2.1 on a "virgin" system. I used the online Installer for Windows with 4 paksets (64, 128German, 128CS, 192Comic).My system is WIN10 x64 on an Acer Notebook Aspire E17.
I experienced exactly the same Fatal Error message as above without having installed anything than the vanilla described above.
I tried to disable any paksets, but nevertheless the error message didn't disappear. I tried with today's nightly, the same. There are no mentioned xml / sve Files in the installation folders.
Honestly, I am somewhat desperate now, as I tried all variations of running the .exe for hours. Any idea, what could help?
Cheers
