PDF scanned by Epson ET-2750 won't open in Adobe Reader

[RBR2]

Mac OS 10.13.6 (High Sierra)

Adobe Reader up-to-date

Epson scanning software up-to-date

I am able to print from the Mac and scan, saving the PDF file to Documents or other locations. If I attempt to open the PDF with Adobe Reader, it crashes generating a lengthy error code. I am able to open the PDF file with Apple Preview. If I save the document as a JPEG it opens normally.

Epson tech support said "call Adobe" and that's all.

I would appreciate any insight into this problem.

If I had to guess I would say that the file coming from your scanner isn't actually a pdf file (even if it has a .pdf extension). Preview will open .jpg files.

We can find out easy enough. Open the file in a text editor, you will see the code. Copy/paste the first few lines of code in here.

Thank you for your assistance.

Since posting the question I have discovered that Acrobat Reader appears to be unable to open any PDF files, including downloaded ones and ones created earlier from a variety of sources. I had uninstalled and reinstalled a current version of Acrobat Reader, but the problem persisted.

The one clue I could not make heads or tails of was "Library missing" reason for termination. Here is a portion of the crash report.

Additional information.

I Googled the error and came up with a post I not found when searching the Adobe site in which the OP said he resolved the problem by reinstalling Acrobat Reader. I Googled the download rather than drilling through the Adobe site and downloaded the file rather than using the prior download. I uninstalled the existing install (again) using AppZapper which eliminates various files associated with an app and then installed Reader from the fresh download. Surprise! The second time is apparently the charm. I do not have an explanation for why the first reinstallation did not resolve the problem and the second one did, but it now works!

Thank you for your kind assistance!
