10.3 and 3.1 How to Know if Running 32-bit or 64-bit Version of Progress/OpenEdge
Problem
How can I tell if we're running the 32-bit or 64-bit version of Progress/OpenEdge?
Solution
On a Windows server, the easiest way is to look at the progress.cfg file.
1 On the server, go to Start > Programs > OpenEdge (version #) > Config.
2 When the config file opens, you will see several line items under each product name. Look for the 'Port Number'. On a Windows server, Port # 31 means it is the 32-bit version. Port # 33 means it is a 64-bit version.
