By installing you accept the EULA. [MISSING M16 — EULA text]
C:\SpectraSim\0.6.0a1\ C:\SpectraSim\openfoam\ C:\SpectraSim\runs\ Administrator rights are needed once, for the installation. The short folder name is required by the flow solver. The first start runs a one-minute System check: two small flow solves and one small mesh. If a row does not turn green, use Help → Create support bundle and send the zip to support.
Uninstalling (Settings → Apps → SpectraSim → Uninstall) removes the program files and keeps your projects, your runs folder, the flow solver (shared by every installed version) and your settings.
Silent install, without questions:
SpectraSim-0.6.0a1-setup.exe /VERYSILENT /SUPPRESSMSGBOXES
