Quark uses ClickOnce for deployment to ease the update process and to eliminate the need of administrator permissions to install the Office Add-Ins.

  • ClickOnce deployed applications, by principle, are installed per user and not per machine (i.e. all users), which enables Add-Ins to isolate and not affect other Add-Ins.

  • Installation and updates can be pushed via a web share or a network, however the admin chooses to.


Despite the above benefits, if you still want to install the office Add-In for all users:


  • You can use an alternate installer technology such as Windows Installer, and obviously the installer will require administrator privileges.

  • You will lose the automatic update benefits and would have to consider an alternative process or implementation

  • There are caveats of deploying Office Add-Ins for all users, such as, end users running with standard user privileges cannot install/uninstall or disable an Add-In.


If such an Add-In fails/crashes unexpectedly resulting in the host Office application crashing, the end user cannot do anything to stop the Office application from crashing because they cannot disable the Add-In causing the crash.
