first you have to be sure to load the migration tolls when installing or updating.
Its better to migrate the express tools (fr 2000) rather than the 14 bonus tools as the 14 layer manager didn't work.
I dont have the site in front of me, but several are listed on the aotodeskpointA site. If you need I can email the express PKG that I have in a directory or look up the site when I get back to work.
as a temporary fix I dragged the 14 tools into 2002 and used the start up suite to load it. You also have to bring in the .mnu files. But, this is not the best way.
