1. Re: v11 incompatability with Acrobat 5
Acrobat 5 is too far back for compatibility with Reader 11. Nothing Acrobat that's "pre-8" should be used with Reader XI.
You can download a trial of Acrobat XI and save them with compatibility for later versions. Or, (possibly) use Adobe's CreatePDF online service, but I don't know if it works with files that are already PDFs.

2. Re: v11 incompatability with Acrobat 5
I think the reference to Acrobat 5 is just a confusion: that's software and not a specific file format. Are you really saying that you have old PDF files but can no longer open them?
Several possibilities, including a virus that wipes out PDF files. Can you share one of these files? If you can, don't try to email it, but put it on your own web site, on Acrobat.com, or another file sharing site, and share the address.

3. Re: v11 incompatability with Acrobat 5
And by the way, I have to disagree with the previous post. PDF is designed to be absolutely backwards compatible. There should be no need to ever "save to a newer version". Sometimes an old file is damaged and software is able to repair it in the process, but no valid file all the way from PDF 1.0 is today invalid.

A quick question to the original poster, has a file called contact.txt appeared in the folder with your PDF files?

5. Re: v11 incompatability with Acrobat 5
Test Screen Name:
The files in question are United States Army Center of Military History, The United States Army and World War 2, Set 2 of 7, Pacific War Official History; a 4 disc CD-ROM published by Government Printing Office.
The discs work just fine on older computers (Pentium) running Windows XP.
I now have a Core i5 running Windows 7. The DVD drive acts like the disc doesn't even exist. I can read the directories but none of the .exe files will launch.
I'm at a loss to explain it.
Did this help answer your questions?
As for the contact.txt question; not as far as I can determine. Nothing appears to be on the hard drive or CD-ROM.
I have uploaded what files I could upload to the Acrobat shared workspace (dgdeloach). I hope this helps.

You need to post the shared link in order for anyone to see it.

How do I do that? The input asks for email addresses and nobody seems to want their email address to be public.

8. Re: v11 incompatability with Acrobat 5
The old applications (.exe) files may not work because they are older 16-bit applications which are no longer supported.

9. Re: v11 incompatability with Acrobat 5
I should say that EXE files are not PDF files at all. They are programs. They might also show PDF files, but they aren't PDF files themselves.
What makes you feel that Adobe Reader should be involved? Are there PDF files on the DVD/CD as well?

12. Re: v11 incompatability with Acrobat 5
Sorry, there were several questions, and suggestions so I don't know what "yes" means unless it is the answer to "Are there PDF files on the DVD/CD as well?".
If that is the case, please try to open one of these files. What happens?

Above are addresses for the files posted to Acrobat Workspaces "dgdeloach99". These are just the uploadable files from disc 1 of 4.
To Test Screen Name:
All .pdf files on disc 1 opened just fine when I tried. It seems that the problem may be isolated to the .exe files which the workplaces website would not allow me to upload.
I hope this provides a little better insight.
Thanks.

The PDF files do indeed sound fine.
The EXE files will be programs, which might be designed to show PDFs, but which are not themselves PDF files. You'd need to take up any problems with the programs up with the makers of the disk, EXE files can only be fixed by the people who make them.

15. Re: v11 incompatability with Acrobat 5
Sorry for all the hassel over the last few days.
Further testing has revealed that the problem appears to be hardware related.
The DVD/CD-ROM in the laptop, appears to be kaput. Sometimes it will read some .pdf files, sometimes it won't. The drive refuses to open or play any DVD inserted into it. I will be taking this stupid laptop in for maintenance.
My sincere thanks to all who tried to assist me with my ******* problem. Thank you all.
