Here is basic information to load a copy onto your own machine:
Download the two files in a directory in which you plan to keep the
simulator.
Unzip the first file which is the simulator itself.
Run setup.
Cancel out of the installer when it prompts for "Setup Needs
The Next Disk."
Unzip the second file which is the license manager. Say okay to each case where a new file
overwrites an old file.
Run setup.
Both files produce a setup file with the same name. If you unzip both
before running the first setup, the setup file will be overwritten by the
second one.
