Versions of the
CICS® Universal Client earlier than version 6 allowed COM libraries to
be registered as in-process (DLL files) or out-of-process (EXE files). From
version 6, only in-process libraries are supported. If you registered COM
libraries as out-of-process with a version of the
CICS Universal Client earlier than version
5, unregister them before installing the product. Issue the following commands
from a command prompt:
ccloepi /unregister
ccloeci /unregister
