I just started to use LaTeX and I have the following error running the blank university template using TeXworks:

! LaTeX Error: File `isodate.sty' not found.

Type X to quit or to proceed, or enter new name. (Default extension: sty)

Enter file name:

I can run older templates without problems as long \RequirePackage[english,ngerman,num]{isodate} is not written in the .cls file.

Is there an error in the template or do I just miss something?

  • This means, that you have not installed the isodate.sty. Try this for a dirty fix: create a the file isodate.sty where the .tex is you are trying to compile. Now open the file and copy the content of this in there. Try to run your .tex again. – Dominikus K. Apr 5 '13 at 10:53

    Sounds that you have not installed package isodate on your computer ... Use the package management system (depends on your used tex distribution) to download and install it. – Mensch Apr 5 '13 at 10:53
  • I used the MiKTeX Package Manager to install isodate and substr. Everything works fine now. Thank you. – C.Colden Apr 5 '13 at 11:02
