Firewall Configuration Note
License activation runs over HTTPS (port 443) – a port that is open in most networks anyway. Only behind a restrictive firewall do you need to add the following outbound rule:
- Direction: Outbound
- Protocol: TCP
- Destination Host:
activation.vicus-software.com - Destination Port:
443(HTTPS) - Action: Allow
To test in PowerShell:
Test-NetConnection -ComputerName activation.vicus-software.com -Port 443 If "TcpTestSucceeded" shows "True", the connection is working correctly.
Installing VICUS on Linux (Flatpak)
VICUS is distributed as a signed Flatpak repository.
1. Prerequisites
You need flatpak installed:
# Fedora (preinstalled on Workstation) sudo dnf install flatpak # Ubuntu / Debian sudo apt install flatpak # Arch sudo pacman -S flatpak
Then log out/in once (first-time Flatpak setup). No other setup is needed — the VICUS installer automatically pulls its KDE runtime from Flathub.
2. Install VICUS
One command (recommended):
flatpak install --user https://flatpak.vicus-software.com/com.vicus_software.VICUS.flatpakref
This adds the signed VICUS repository, verifies its GPG signature, and installs VICUS together with the required KDE runtime. The first install downloads a larger runtime (~hundreds of MB) — subsequent updates are incremental.
Alternatively (add the repository manually):
flatpak remote-add --user --if-not-exists vicus \ https://flatpak.vicus-software.com/com.vicus_software.VICUS.flatpakrepo flatpak install --user vicus com.vicus_software.VICUS
3. Run
flatpak run com.vicus_software.VICUS
VICUS also appears in your application menu after installation.
4. Update
flatpak update com.vicus_software.VICUS
(GNOME Software / KDE Discover also offer updates automatically.)
5. Uninstall
flatpak uninstall --user com.vicus_software.VICUS
Notes
- All downloads are GPG-signature verified against the VICUS signing key embedded in the repository definition.
- For a system-wide install (all users, needs root) drop --user and run the commands with sudo.
