How to install Flash Components?

programming flash
1

Hi,

I need to install a component to use in Flash. I followed the instructions:
To install an extension (from inside Flash):

  1. Go to HELP > MANAGE EXTENSIONS
  2. Choose FILE > “Install Extension”
  3. Install xxx.mxp

I restarted flash, but now when I open the component window the component is not there. I only see User Interface and Video. Any help would be appreciated, thanks!
