finding excel utilities

I used excel utilities plug-in to exchange x-y data between abagus and excel. but now the excel utilities is not listed in Plug-ins--> tools, all of the other tools existed except the excel utilities. I dont know what happened to this! why is it removed?! I can find it in SIMULIA, abaqus_plugins. would you please help me? how can I add it again to the plug-ins list?
