Do you want to install your EA Add-Ins without admin privileges? This article shows you how to make a WIX installer which supports a non-admin installation of your EA Add-In. If you already have a WIX installer, you see how to make just a few changes to install your EA-Addin without admin rights.

You may also check EXPloring EA, Non-admin installation of AddIns and Tutorial, Geert Bellekens: Addin in 10 Minutes.

All here described you can see in the Open Source hoTools (see GITHUB) projects:



With WIX Toolset for creating your *.msi installer file you can make:

  • Simple non-admin installer, per user installation
    • Modify your WIX installation with just a few modifications
    • No admin privileges required
    • No dialogue, just click and eberything runs almost invisible
  • GUI for per-user (no admin required) or per-machine installation
    • Make your WIX Installation with GUI where you can choose
      • per-user (no admin required)
      • per-machine


A per-user installation doesn't need any admin privileges. If you want to install your EA Add-In as per-machine installation this is only possible with local admin privileges.

The Microsoft Installer , Single Package Authoring, can install per-user without admin privileges. No admin install needs some precautions:

  • Install in 'LocalAppDataFolder'
  • Register Add-In in 'HKMU'
  • Register the DLLs in 'HKCR'
  • Say the installer you want per-user with limited privileges
    • InstallScope='perUser'
    • InstallPrivileges='limited'

Make it easy:

I'm a German freelancer in the area of Enterprise Architects and software/system engineering. A large part is embedded and Functional Safety with EA. But not only...
According to Albert Einsteins aphorism "Make things as simple as possible, but not simpler” I like to smoothen work with Addins and an easy to use EA Tool integration in a complex development environment. Another step in my opinium are lively workshops to get an enjoyable and long lasting launch of the daily EA work.
Well, of course that’s not all and you have therefore good reasons to contact me. See you….
