My Outlook addin is not loaded and adxloader doesn't seem to run

I have an Outlook add-in written in .NET 4.6 which runs correctly in test environments, but fails in production.
In production the addin is correctly installed, but Outlook can't open it.
Every time I reactivate the addin in the registry and start Outlook, the Add-in is moved to Inactive Application Add-ins, and the error is:

“Load Behavior: Not Loaded. A runtime error occurred during the loading of the COM Add-in”.

I tried setting generateLogFile="true" and <logFileLocation> in adxloader.dll.manifest, but no log file was written.

Same error occurs when the anti-virus is disabled.

Is there some way to check when adxloader is called?

Could adxloader run without writing logs?

If Outlook fails calling adxloader, are errors logged somewhere?

Versions: add-in is compiled for .NET 4.6,
runs ok in Windows8 64bit+Outlook Pro Plus 2013, Windows10 64bits+Outlook Pro Plus 2016 32bits,
fails on Window 7 Entreprise 64 SP1+Office Pro Plus 2016.

Best regards,

Hello Martin,

I'd reinstall the add-in and check if there are any issues in adxregistrator.log. If there are no issues, check section Troubleshooting add-in loading, see the PDF file in the folder {Add-in Express}\Docs on your development PC.
