Can't load attribute assistant?

Question

Hi All,

I've downloaded the latest version of the attribute assistant from here:

Attribute Assistant | ArcGIS Solutions

Requirements says: ArcMap (Standard or Advanced) 10.2.1, 10.5 - 10.8

I'm running:

I get the following error:

I've tried running ArcMap 'as administrator'... same result.

Any ideas?

Thanks

Fred

Just in case anyone else runs across this ... apparently you can't add the extension via the 'Addin Manager/Customize' dialog.

Just double-click/execute the add-in with all the arcgis apps closed.  As per the doc:

Install add-in - Attribute Assistant | ArcGIS Solutions

RTFM ..
