I'll try ...
Basically you need two things ( assuming that we are talking about an application that is based on the classic GUI ):
The Progress installation
Most likely you will need to install at least the client networking license from Progress. That will give you the prowin32.exe which is the AVM ( ABL virtual machine ) on which your application will run. During the installation you will be asked some things. The most important ones are things like languages and code pages. Based on you choices some files in the installation directory will be customized - most prominently the startup.pf. I always recommend to do a full installation because otherwise you might end up missing things like the ODBC/JDBC drivers.
You need to gather all the relevant information before you begin with the installation. I strongly recommend you to read the installation guide to get an idea.
Your application:
Most likely your application will consist of a buch of .r files spread over a directory tree, an ini file which contains the DLC, PROPATH setting and other stuff related to your application, and, a start parameter file that contains customized start parameters for your application.
Unless your applications contains third party software that need to be installed ( like special OCX controls ) all these files are just copied into the correct directory on the target system.
Next you create the short cut pointing to the prowin32.exe and a usually a working directory set to the root of the directory tree I've mentioned above and you're done.
This how your short cut
_COULD_ look like:
C:\Program Files\Progress\OpenEdge\bin\prowin32.exe -basekey "INI" -ininame your.ini -pf your.pf
The -basekey "INI" is responsible for telling the AVM not to look into the registry but relative to your PROPATH in the file system instead -which is what I prefer personally ( I think the Windows registry is a dump for each and everything ... ).
Disclaimer: Everything I told you is typical usage. You need to customize these so that all these suits your needs.
