The password you need to enter is your Mac password. When installing software on Mac, Mac requires a user (administrator) password in order to install the software.
P.S. You created two identical threads. I have deleted your other duplicate thread.
Thanks for the reply, but i have tried that password as well. That is why I am stuck! I made a new password following adobe directive and I am sure I entered my mac password correctly. Any other thoughts are appreciated. thanks again
