I've encountered this problem before - but I forgot to document the solution:
In a new installation of my program on a customer's PC (Windows 10 pro) reports simply don't show. Preview as well as printig looks like working with an empty result cursor.
On the same machine I can use VFP9.exe to generate and preview a report on the fly with tahe same tables.
All report (preview, output) APPs are present and current.
A default printer is installed and works properly.
Any idea?
