I have tried several options but failed to open my PDF file with all versions I have tried. Other versions either say it is not the right format or that but it is corrupted PDF Reader 3.26.3 which works on Android mobile devices was able to open it. All my clients who visit my website complian about this problem, so I request that they download PDF Reader 3.26.3 ajdbuse for that purpose which makes the process cumbersome for those who already have other versions of PDF readers. What would you recommend as a way out especially seeing that most clients use desktop applications for this purpose and I can't find an equivalent of this working Android version in the desktop windows Operating System. Ibhave attached a file I used for the above explanations. It opens with PDF Reader Version 3.26.3 but fails with other versions.
You don't mention any Adobe products but you imply that multiple other PDF readers have issues opening your PDF file. This is probably indicative of a malformed PDF file that the third-party PDF Reader 3.26.3 is able to open, probably because it is ignoring possibly very serious errors in your PDF file.
If you can post or point to the PDF file, maybe someone here might be able to ascertain what is wrong with the PDF file you are distributing.
