Addin will only run if Word is run as Administrator

Question

_{Tuesday, September 20, 2016 2:30 PM}

I have an addin for Word 2016 that was made inhouse, but it will not run unless you open Word as administrator, then it works fine.  The addin manifest files are stored on our Sharepoint server and we are Federated and use SSO.  The thing that I notice is when I run Word as admin and load the addin a sign in box displays very briefly then closes and the addin loads.  Has anyone experienced anything like this or know what could be blocking the addin if Word is run normally?  Thanks

Hi,

Please make sure your Add-in is the same bit version (32bit or 64bit) version of your Office applications.

Additionally, please open registry editor and navigate to “HKEY_CURRENT_USER\Software\Microsoft\Office\Word\Addins”. Check the LoadBehavior for this specific add-ins. By default, this entry is set to 3, which specifies that the VSTO Add-in is loaded at startup.

I originally posted under the name sid12399, but for some reason I couldn't reply to you.  This didn't work.  I figured it out.  I went to Internet Options, clicked the Security Tab and enabled Protected Mode for Internet zone.  Thanks for your recommendation though!

These steps worked for me even though my issue was with a Legal Files (Case Mgmt. Soft) add-in. Thank you.
