Silent Uninstallation

A silent uninstallation refers to uninstalling in the background without displaying the UI, in the same way as with a silent installation.

Desktop supports silent uninstallations.

NOTE

An error is displayed and the installer stops if you enter a parameter as indicated below.

If you specify a parameter other than the available parameters

If you enter the same parameter multiple times

If you enter contradictory parameters, such as trying to start the installation mode and uninstallation mode at the same time

The silent mode does not display messages when errors occur, except for items controlled by Windows such as UAC.

A silent uninstallation performs a different operation according to whether Desktop is already installed.

Operation	Desktop Installation Status
Stop the process	Desktop is installed with a different license status A version of Desktop different from the installer is installed Desktop is not installed
Start a silent uninstallation	A version of Desktop the same as the installer is installed (*The process can start if the first number of the version is the same)

A detailed parameter file is not required to perform a silent uninstallation. If a file is specified in the command, it is ignored and an error does not occur.

Prepare the installer used to install Desktop.

Start Windows and log in to the system as a user with Administrator privileges.

Use the command prompt to specify the file path to "setup.exe" and execute a silent uninstallation.

Example) For 32-bit operating systems

Start the command prompt and enter the following.

(Path to the folder that the installer was placed in)\32bit\setup.exe /qn /x

NOTE
In the above example, the "/qn" refers to starting the installer in the silent mode, and "/x" refers to starting the installer in the uninstallation mode.
