Yes, that should be the correct directory - at least if the MIBDIRS environment variable isn't defined
and pointing to another directory (that could be the case if you have installed some other
program that uses ucdsnmp/Net-SNMP that has set the MIBDIRS environment variable).

Please note that there should be semi-colons instead of colons between the different MIB-names (on Windows).
If you installed Ethereal a while ago, then probably you have colons - and then it will not work.
Replace them with semicolons or replace the list of names with ALL  (if you want all of the MIBs in the directory to be
loaded).

You can configure Ethereal to display warnings  in a console window.
Do this from Menu item: Edit/Preferences/  UserInterface/Open a console window: Always (debugging).
It might give some hints.
