I am compiling code pulled from our source control (that is currently in production). Everything compiles fine, but when I try to run our system program, I get the following error and I don't know what to do. I've only been coding in Clarion for a little over a year, so I'm still learning. Can anyone PLEASE give some insight?

Try to build the app in debug mode, also replace ClaRUN.dll with bin\debug\ClaRUN.dll, this may help to get more exception details.

With your collect.app opened, click on the “Build” menu at the top of the IDE, then “Set configuration”, and make sure “Debug” is selected.  
When you compile/run, (and use the debug ClaRun as Mike suggested) it should help give you a better idea next time it crashes.

As Mike and Jeff suggested, use the bin\Debug\ClaRun.DLL  
here’s how to do that
