You will receive a DLL registration error when trying to install the export process in the Kofax Administration module. As of the date of this article, OpenText have stated that they have received a number of support cases concerning this issue, but they do not have a fix yet. Manually registering the DLLs does not seem to resolve the issue.

Install ApplciationXtender v8.1 Document Manager with the Kofax Export script and use this to release to AX v16.3.
