Hi,

by using sledgehammer, i get this:

"z3": A prover error occurred:
The SMT solver Z3 is not activated. To activate it, set
the environment variable "Z3_NON_COMMERCIAL" to "yes",
and restart the Isabelle system.
See also "/cygdrive/c/Users/DRaco/Desktop/Work/Isabelle2013-1/contrib/z3-3.2/etc/settings"

I went to settings and "Z3_NON_COMMERCIAL" was already set to "yes".
What now?

Thanx!

But probably the line was commented out. If the first character is #, delete it (and relaunch Isabelle).
