How do I install / uninstall Vizual silently or by command line ?
On Windows you should run your cmd.exe or Powershell in Administrator Mode, then run Vizual installer executable with the /S argument, for example in Powershell : ./"Vizual v1.1.0 Installer.exe" /S if you're in the extracted folder from the downloaded zip. Same goes for the uninstaller but you'll also need to specify the -Uninstall_Vizual argument.
If you want to be sure that the installer / uninstaller exit automatically without user confirmation you should run the .exe like this instead start "Autokroma" /wait /b "PathToInstallerOrUninstaller.exe" /S
