When following the SOI 4.3 CU3 Installation Instructions, users are directed to run a tool named registrydownloader.bat.
However, the tool is missing from the environment, and the following symptoms are observed:
This is a documentation error in the SOI 4.3 CU3 Release Notes. The WSO2 service (Catalyst Registry) was removed from the product starting with SOI 4.3 CU2. Because the service is no longer used, the registrydownloader.bat and registryloader.bat utilities are obsolete and were removed from the installation media and target directories.
The step requiring the execution of registrydownloader.bat can be safely ignored.
Documentation will be corrected soon.
