Got the latest FileDefinitionManager 5.4.21 from support portal. After unzip into separate folders, can open all other executables as standalone apps but CATDMFMforIMSIntegrator executable doesn't open, no error, just no action is seen, no process is started.
Tried opening in command prompt and "as administrator" but nothing works.
Release : 5.4
Component : Mainframe
CATDMFMforIMSIntegrator is not supported now and it has not been touched since last 4 years. We acknowledge that the latest build is having issues.
The solution is to use the last working version which is 5.4.16.
