Hi @rosalynh54925908,

Assuming you mean Adobe Acrobat 5 and the files in question are PDF, try using a modern version of Acrobat.  Do not use your browser's built-in PDF viewer.

FREE Acrobat Reader -- view, comment, print & sign PDF.

Paid Acrobat Pro DC -- the complete solution for creating and saving PDF.

What is an "Adobe 5 file"? Over the years, Adobe have made hundreds of apps, many of them made it to version 5?

As well as the app, please give exact text of errors.
