Install Notes:

You will only have to run this installation once. 

This install does two things:

1. It updates these three system libs:

svcp60.dll
msvcrt.dll
mfc42.dll


2. Creates the ERDAS registry key.  

"HKEY_LOCAL_MACHINE\SOFTWARE\ERDAS\Imagine\8.4" 


Finally, since some system files are updated,
you must reboot your system before continuing.

No software is loaded during this installation process.

There is no uninstall procedure.
