Use the --mode unattended parameter to uninstall Archicad or Add-ons in unattended mode.
Notes:
–Be careful when adding parameters using copy/paste, because sometimes the two dashes are converted into a single dash, which will cause errors.
–The following examples assume that the program(s) were installed to their default location. If the --installdir parameter was changed for installation, then the path shown below must be modified accordingly.
