I've received a number of PDF files from a colleague using a Mac (OS10). When I copy them to my Win XP (SP3) PC, and try to open them with Adobe X or Reader 11, the file names are dimmed in the list, and Open results in an error message that the file is corrupt or not a PDF. If I copy the files to a laptop running Win 7 (Home Prem), they appear normal, and can be opened by Adobe or Reader. I don't believe this is related to Protected Mode in Adobe, as the same problem happened with Foxit Reader. Anyone have any ideas?
Here's a link to one of the files in my Dropbox: https://dl.dropbox.com/u/23951615/._Arndt%2C%20W%2C%201965%2C%20The%20 Dreaming%20of%20Kunukban%2C%20Oceania%2C%20Vol.%2035%284%29%2C%20pp.%2 0241-259.pdfhttp:// .
Thanks for your interest.
I seemed to have trouble downloading, but think I got it. The file is named "_Arndt, W, 1965, The Dreaming of Kunukban, Oceania, Vol. 35(4), pp. 241-259.pdf". I got an error when trying to open as a PDF. So I took the next step and opened in notepad. A PDF should start with text like "%PDF-1.7" with the 1.7 denoting the version of PDF. The remainder of the file would be filled with various blocks that define the PDF (not going there as I do not even know the standard).
Your file started out as "<!DOCTYPE html><html lang="en" xml:lang="en" class="" xmlns="http://www.w3.org/1999/xhtml">" and was filled with html. It is obviously not a PDF file. Again, I assume I am looking at the correct file. If you change the extension to html and try to load it in a browser, it starts trying to load other stuff, leading me to immediately close it. I have no idea how your colleague created the files, but they are not PDF files and it looks like he simply tried to save an HTML page and name it as a PDF, thinking that would give a PDF.
Anyway, the file is not a PDF.
Thanks for you help in this. I suspect the problem is other than what you
said, as I was at his desk and saw the files open on his Mac as PDFs, and as
I said in the original question, they open OK on my Win 7 laptop. Probably
what you saw from the Dropbox link was something Dropbox did to the file.
Open the file in a text editor and check the starting text. It should read %PDF-1.7 or such as I suggested. If it does, then the post got messed up. If it does not, then you are not looking a valid PDF.
Using TextEdit, the same file comes up on my Win XP machine (not including
all the "NUL"s) as "Mac OS X", then a bunch of "NUL"s, and then "PDF". I
thought Adobe designed PDF as a cross-platform standard, but I have had this
problem before from this source, who always uses Mac, and this suggests that
something in his OS is stamping the PDF files as Mac OS X. Does this make
I can email the PDF to you as an attachment so you have it without any
interference from Dropbox, if you would like.

I've never had a problem reading or using PDF's from PC's nor PC
Sure go ahead and send me directly.
Your file from Dropbox opened normally as a PDF on my Win XP machine. I agree re your comment about PDFs from any source should open OK, and I've asked my source to take it up with his IT people (he's located at a university).
What you are reporting as the beginning of the file points to a definite error. PDF files always start with "%PDF", providing a quick check for an invalid PDF. Note I pointed to invalid since the existance of the proper start does not insure the rest is valid.
I'm having the Same problem with XI Pro running on windows 8. I receive PDFs from the Secretary of State office all the time and about half of them will open. Half the time I get the error message the file is dammaged and cannot be repared. Everytime I can open them with no problem on my laptop running Adobe X Pro and windows 7. The problem is with XI. I've reinstalled it and that didn't help.
