It sounds like you need to download and install the data files for Moldwizard. From the product download server, select "NX > Product Updates > Moldwizard > Nx11" and you'll find:
You may also need to set MOLDWIZARD_DIR as explained here in the documentation.
I install Moldwizard the same way file : " mwnx11.0_data.README.txt " but i can't do that , when i create new project , on Assembly Navigator not have appear all file assembly for Mold Base
It appears that NX is not reading the moldbase_reg_mm.xls file in %MOLDWIZARD_DIR%\moldbase\metric\
First check that the moldbase_reg_mm.xls file exists in the above directory.
If the file exists, try manually adding the Moldwizard Add-In to Excel. From an Excel session (with a blank file open), select "File > Options > Add-Ins" and at the bottom of the page select the "Go" button for "Manage: Excel Add-Ins". Hit the Browse button and navigate to %MOLDWIZARD_DIR%\templates and select moldwizard_add_in.xla. Choose OK, make sure the Add-In is checked, and choose OK again. Restart NX and see if the DME folder now contains mold bases in the Member Select window.
