I have enabled and attached several PDFs to a feature class in ArcMap. I created a package layer and added it to Explorer Desktop. The attachments are not listed in the popup. I looked online for help and I'm not sure if I haven't enabled something in Explorer Desktop or if there is another issue.
Any ideas?
I'm thinking you are running into a known bug- NIM073410: Attachments in layer packages are not available in ArcGIS Explorer 1750. Please feel free to contact Support Services if you would like your account to be attached to the incident so that you can track its status.
