I tried Scidavis 2.7 (fresh install on a computer without scidavis) but unfortunately the issue is still present.
SciDAVis 2.3.0 is not affected. Installing scidavis.2.3.0-win-dist.msi after installing scidavis.2.4.0-win-dist.msi solve this issue.
Can't change language preference (scidavis 2.4.0 windows)
