I use newer ADS versions now, and don't have the old ADS2009 available, so I can't check this for you.
Did you download the correct designkit version (for ADS2009, not 2011/2012)?
Did you install the designkit as described in the ADS online help?
Check if your design kit installation path has a space (" ") in the path. That will cause this error message.
If yes, uninstall the designkit and re-install into a path with no space in the name.
sir this path i am giving in design kit =C:/Documents:idea:and:idea:Settings/Administrator/Desktop/extract/nxp_rf_smallSignal9/
sir one more error i am getting is =(de_load_item_symbol_image)cannot load component symbol............................is this is the reason of my error.
