You need to set option afx_enabled to yes in your config.pro and restart Creo. After restarting you should be able to access Framework tab from the assembly level.
also Advanced Framework Extension option must be checked during installation.
Look, whether Creo2_LOADPOINT\Creo 2.0\Common Files\Mxxx directory contains efx subdirectory.
tnks...i tried it still not wrkng...i use creo parametric 2.0 M010........efx file is installed in the m010 file and also i m trying in asembly mode only....why isnt it wrkng?
1.] check if your config.pro file contains options ... afx_enabled yes
2.] create new assembly, then publish picture of current Creo window ... I need to see ribbon interface
