I'm using TeXmaker on Windows 7. When I tried to add the diagbox and glossaries packages in my document and I compiled, it errored and printed:
!LaTeX Error : File 'glossaries.sty' not found. etc ...
Any ideas as to why this is?
This usually happens because you did not refresh the database. To refresh the database of the packages, do the following:
open MiKTeX options (from your start menu)
In the General Tab (click on refresh FNDB).
Refer to my answer at Installing packages with miktex 2.9
