I get the same error as reported here. An update of miktex did not help so I am at a loss as to how to proceed. The example works just fine on a different machine.

  • You shouldn't be using $$...$$, but \[...\]. I get no errors after removing the % characters; more information about the system where XeLaTeX fails is necessary. What version of MiKTeX is running on it? – egreg Mar 24 '14 at 13:11
  • @egreg I tried [ but get the same error. ($$..$$ worked just fine on the other machine). Miktex is 2.9. What could be going wrong here? – Felix Goldberg Mar 25 '14 at 14:57
  • Add \listfiles and compile on both machines, then compare the lists to see where's the mismatch. – egreg Mar 25 '14 at 15:08
  • I didn't get any error with your example. Using MikTeX 2.9 (but not recently updated). Is it possible that some recent behavior change caused this? What other OS+TeX distro combinations have you tried? ... Also, please try to further reduce your example. – einpoklum Mar 25 '14 at 17:32
