Resolution

How to resolve the "This advertised application will not be installed because it might be unsafe" issue when trying to install Connexion client.

If you try to install the Connexion.MSI package for the first time on your computer, and you receive the "This advertised application will not be installed because it might be unsafe…change the installation user interface option of the package to basic" error, then install the MSI package by using the Msiexec.exe command with the /qb switch, in order to set the user interface level to Basic UI.  To do that:

  1. Create a new empty folder on the root drive (C:\); call it temp.
  2. Copy the Connexion.MSI package into the temp folder.
  3. Then open an administrative command prompt.
  4. From the command line, navigate to the c:\temp folder; cd \temp.
  5. Type the following command and press Enter: msiexec.exe /i Connexion.msi /qb.
  6. Follow the prompts to install Connexion client.
