Thumbs up PDF file is damaged

Hello,

When PDF files are downloaded, the user receives the following error:

"There was an error opening this document. The file is damaged and could not be repaired".

This error occurs with older versions of Adobe Acrobat Reader (tested and failed on 6.0, 7.0). The code I am using is pasted below and is a collaboration of research I've done on EE and google.

Note: The file that is streamed to the user has a higher file size than the actual file. You can see below I have tried using different headers, pdf and octet-stream.

We must maintain the ability of allowing the client to download the pdf file rather than it opening in the browser.

Any help is appreciated.

Thanks.

I see no code...

If you upload a file to a server and the copy that people download has a different file size, I'd say your server is broken and is mangling the files.

Thumbs up

Apply next steps...

< Navigate to the location with the corrupted PDF file. Right-click on it and select "Rename." Type any other file name and hit "Enter." Sometimes, a simple rename can troubleshoot corrupt PDFs.
< Make sure your Adobe Reader is in working condition. Open any other PDF files on your hard drive to make sure the problem is not originating from your Adobe Reader. If it does, reinstall Reader from Adobe's website for free.
< Update Adobe Reader. Launch Adobe Reader from the Start menu under "All Programs." Click on the "Help" tab and select "Check for Updates..." Follow the on-screen prompts to complete installing the updates. Try re-opening the PDF file.

Helpful resource, which might be effective to know more about different resolutions...
