Is there a recommended procedure or best practice information regarding the installing of a second instance of WorkflowGen on the same machine?
Website root directory
We usually recommend installing the two sites under their own root folders.
For Workflowgen version 5.x only
FdfApp and MsScriptControl
You don’t need to install these COM+ twice. Both sites will use the same COM+. Just make sure they are registered properly on the Windows server machine.
