This will be much easier in the next release when WinGet installer is completed. There was an issue with the current installer that was killing all processes named Pritunl.exe to close the GUI client before installing. A fix has been implemented for this but won’t be available until the next release. This won’t cause issues when running the installer normally. But when it is run in silent mode it will fork the installer and return an error on the original process. This will cause any automation software to believe the install fail. The Pritunl.exe installer should be renamed to avoid this issue.
