Corrupt downloads of .pdf files

By marc_lees ·
Our customers download data (Acrobat.pdf files) from our website. Broadband users seem to be OK, but slower dial-up ISP users get unreadable files although the download reads complete & OK.

Corrupt downloads of .pdf files

by maxwell edison In reply to Corrupt downloads of .pdf ...

"Adobe Acrobat .pdf Files Appear as a Blank Window or Frame (Q177321)"

SYMPTOMS:
When you try to view a Portable Document Format (.pdf) file in Internet Explorer, you may see a blank window or frame instead of the .pdf file. This may occur even though you have installed the Adobe Acrobat Reader program, and you are normally able to view .pdf files in that program.

CAUSE:
This behavior can be caused by any of the following situations:

An updated version of Adobe Acrobat Reader is required to use in-place activation. In-place activation is a function that opens a program file in Internet Explorer and displays the toolbars from the associated program.

The security level for this zone is set to High in Internet Explorer 4.0, 4.01, or 5. For information about security zones in Internet Explorer, please see the following article in the Microsoft Knowledge Base:

Q174360 How to Use Security Zones in Internet Explorer 4.0

Ratings are enabled in Internet Explorer 3.02, or the safety level is set to High.

The .pdf file is being served from an early version of some Web servers (such as Microsoft Internet Information Server version 2.0).

This can be related to a slow connection, the server has a high load, or the .pdf file being very large.

You are running a version of Internet Explorer earlier than Internet Explorer 5.5.

This issue may be caused by a corrupt ActiveX control. In order for Adobe Acrobat Reader 4 to use in place activation with Internet Explorer, the file Pdf.ocx and Pdf.tlb must be present in the folder x Program Files\Adobe\Acrobat 4.0\Acrobat\ActiveX\ where x is the drive letter where Adobe Acrobat Reader was installed. If either of these files are missing, Internet Explorer may show a blank window when opening a .pdf file.

Good info and applies to some situations, but this particular function seems to be in the corruption in the download procedure.

Hi,

There is a tool called Advanced PDF Repair. I have used it to repair many corrupt PDF files on successfully. Its homepage is http://www.datanumen.com/apdfr/

Maybe you can ask your customers to have a try.
