You do not need to install Eclipse 3.7 to work with MyEclipse 10. MyEclipse 10 is based on Eclipse 3.7, so there is no need to have a separate install of Eclipse 3.7.
I suggest using Pulse to install MyEclipse 10. Here is an FAQ on how to install through Pulse :

The FAQ is based on earlier versions of MyEclipse. Choose ‘Eclipse 3.7 – Indigo’ for MyEclipse 10 and follow the steps accordingly.
Let us know how it works for you.
