That's not caused by Geneva, of course.
It's possible that, instead, some other software you have installed, maybe the antivirus, has corrupted one of our modules that are required by the scenery to run, possibly because it has mistakenly confused it as a threat.
Try to do as follows:
- Reinstall Geneva again, but turn off the antivirus while installing.
- BEFORE turning the antivirus back on, configure it to exclude the whole Addon Manager folder from scanning.
