Error [PDF Structure 40]

rumboy · Post by **rumboy** » Mon Sep 10, 2007 3:46 pm

I am having trouble opening the attached PDF's with XChange Viewer. I get the following errors when trying to open them:

Error [PDF Structure 40]: Invalid file format
Error [PDF Structure 40]: Reference table (xref) not found

One was sent to us from an outside vendor and the other was generated by a third-party software package that we own. I am currently using Xchange Viewer Version: 1.0(Build 0024). Both of these files can be opened with Adobe Reader 8.

Please advise how to fix this.

Both of these files are corrupted and please notice that when you open them into Adobe Acrobat it recovers them and asking for save when you try to close document.

PDF-XChange viewer for now doesn't support such type of recovering, but hope this will be realized soon.

When I open and close them with Acrobat 8, I get no such recovery message nor does it ask me to save them when I close the document. Is there something I need to turn on in Acrobat to get those?

Any idea on when there may be a release that will support this? I will need to switch many of the users default PDF reader back to Acrobat until this is fixed. Thx.

Do you use whole Adobe Acrobat or Acrobat Reader ?

Best case is to use not corrupted PDF files -- I cannot promize when our recovering option will be realized.

Acrobat Reader 8. I agree that using non-corrupt files would be the way to go. The problem is that I don't have control of the creation of either of these files. Therefore it is hard to control the corruption. I'm sure nobody has complained to the creators because most people use Acrobat Reader that doesn't have a problem with them.

Yes, Adobe Reader will not offer you the chance to save, because in most cases it does not support this functionality.

We are just downloaded the new build (25) to try out PDF-XChange in our organization. I just received a query on a PDF Structure 40 error message which the user got while attempting to save a (BMCSoftware)guide she had highlighted (extensively).

'Error saving document to "{local UNC path to server}": Error[PDF Structure 40]: Invalid Object Structure'

I have been able to mark up/highlight documents and save (copies), but get this error mesage when I try to re-open any of them. Originals open and close fine.

I am amending my original post with new info. I believe by problem to be due to network storage (??). If I save docs locally, they work fine. If I save to any network store, either virtual or UNC, they will not open. If I copy locally marked files to a network location they still open fine.........
