Uninstalling Qlik NPrinting Server

You can uninstall the Qlik NPrinting Server using the user interface or the command line interface (CLI).

Configuration files

The Qlik NPrinting uninstallation process deletes the app.conf proxy configuration files:

• %ProgramData%\NPrinting\newsstandproxy\app.conf
• %ProgramData%\NPrinting\webconsoleproxy\app.conf

If you re-install Qlik NPrinting, either in the same computer or in another, you will need to re-apply all the edited settings.

You can keep a copy of the files to record which configuration options were changed. Do not overwrite any app.conf configuration file with an older version as some configuration options may be different. You can overwrite the app.conf configuration files only if the replacement is from the same release of Qlik NPrinting.

The proxy configuration files for Qlik NPrinting 17.3, including service releases, had the following paths:

• %ProgramFiles%\NPrintingServer\proxy\newsstandproxy\src\qlik.com\newsstandproxy\conf\app.conf
• %ProgramFiles%\NPrintingServer\proxy\webconsoleproxy\src\qlik.com\webconsoleproxy\conf\app.conf
