Systems Management

since tightvnc is easy installabe via MSI you should use a simple distribution (Managed Install) 
For all options you can use in the one liner see the official documentation:
https://www.tightvnc.com/doc/win/TightVNC_2.7_for_Windows_Installing_from_MSI_Packages.pdf

So the line would be:

msiexec /i tightvnc.msi /qn /norestart ADDLOCAL="Server,Viewer" VIEWER_ASSOCIATE_VNC_EXTENSION=1 SERVER_REGISTER_AS_SERVICE=1 SERVER_ADD_FIREWALL_EXCEPTION=1 VIEWER_ADD_FIREWALL_EXCEPTION=1 SERVER_ALLOW_SAS=1 SET_USEVNCAUTHENTICATION=1 VALUE_OF_USEVNCAUTHENTICATION=1 SET_PASSWORD=1 VALUE_OF_PASSWORD=PASSWORD SET_USECONTROLAUTHENTICATION=1 VALUE_OF_USECONTROLAUTHENTICATION=1 SET_CONTROLPASSWORD=1 VALUE_OF_CONTROLPASSWORD=PASSWORD

Please note: I personally like to use the following setup in a MI:
Override alternate installation and check Do not prepend msiexec

This is easier for me if some installer is using a crappy setup with other parameters than the default setup needs.
