I have been receiving "Insufficient data for an image" with Adobe reader version 2021. I uninstalled and reinstalled however still the same.
I've moved this from the Using the Community forum (which is the forum for issues using the forums) to theAAcrobat Reader forum so that proper help can be offered.
Generally the message is simply telling you, truthfully, that there is an error with the file.
The error is with almost all the files. Mostly after 10-15 opening the file the error pop-ups on the screen.
The files. Where are they from? Please be as detailed as you can without revealing private info.
The issue is with every file coming from various sources. Some are scanned and some via email from different sources.
If they are from different sources, and there are are any that contain no sensitive data, perhaps you share one and post a link. Or even post 2 from different sources.
