How do I get rid of this error:

PDF inclusion: found PDF version <1.5>, but at most version <1. 4> allowed

I tried putting \pdfoptionpdfminorversion=5 after my preamble, but nothing happens.

(Edit added by Andrew Stacey):

I've seen this error in the following situation.

  1. I created some PDFs using TeXLive2010 with the most recent stable PGF/TikZ (in case it is relevant).
  2. I cropped these PDFs using pdfcrop, again from TeXLive 2010.
  3. I sent these to another person, who included them in their document with the graphicx package.
  4. That person used TeXLive 2009 to compile the document.

(I'll need a little time to dig out a MWE! I'll need to figure out how to switch between TL2010 and TL2009 on my machine.)

Are you including any other PDFs as pictures? Check the PDF version of them. Which version of pdflatex are you using? – Martin Scharrer Feb 22 '11 at 9:37
I have two pdfs as pictures, how can I find out what version of pdflatex I'm using? – user3749 Feb 22 '11 at 9:45
Both the PDFs are 1.5 – user3749 Feb 22 '11 at 9:47
It is in the first line of the log file. Also check the PDF version of the resulting PDF. – Martin Scharrer Feb 22 '11 at 9:49
Where's the $log$ file? Sorry, I'm new at this :S – user3749 Feb 22 '11 at 9:55

Did you try \pdfminorversion=X ? At least it works for me...

Then it says ! LaTeX Error: Missing \begin{document}. – user3749 Feb 22 '11 at 9:57
when I have \begin{document} below it – user3749 Feb 22 '11 at 9:57
\documentclass{article} \pdfminorversion=6 \begin{document} Text \end{document} This is the right syntax and should run. – meep.meep Feb 22 '11 at 10:06
now it says geometry driver: auto-detecting geometry detected driver: pdftex and it doesn't finish and get the PDF to be previewed. – user3749 Feb 22 '11 at 10:08
This is no way to solve your problem. No one can find the mistakes in just tiny bits of code an error messages. You should post a minimal example (see the FAQ) please. – meep.meep Feb 22 '11 at 10:12
