After many failures, I think I finally have a working Win 7 installer for EPE. The link can be found on Post #1.

The installer is only required on the first installation and if the program is complaining about missing OCX or other library files. After that, you can only overwrite the installed EPE by the new version.

kudos: I want to thank VersatileGuy for his help in creating this working installer. His knowledge and help were really appreciated. Thanks.
