I want to create a poster using beamerposter. I am trying to compile this example from the package documentation.

Without touching anything, when I compile the example-style-I6dv.tex, I obtain 75 errors. I have beamerposter.sty and beamerthemeI6dv.sty in the project directory, so I don't understand why this example is not compiling smoothly.

Sample of errors that come up from the beamerposter.sty:

./beamerposter.sty:0: You have requested, on input line 42, version`2006/11/18' of package xkeyval,but only version`2005/01/30 v2.0 package option processing (HA)'is available.

What to do?

  • Give a MWE! No one can help with the information given. Call \listfiles before \documentclass and give output. Not that I can help but if you do that, maybe someone else can. Commented Nov 6, 2012 at 22:10

    As per the first error message you posted, the xkeyval package you are using is too old. You may find that you need to update more than just that one package. You did not mention what distribution you are using. Take at look at How do I update my TeX distribution?. Commented Nov 6, 2012 at 22:10

    The xkeyval package has developed quite a bit over the years, and your other errors look related to keyval processing, so as @cyberSingularity this is almost certainly the issue. We'd need to see more of the log to say where xkeyval is being loaded from: you may have an old 'local' version somewhere.
