Do I need to follow the prerequisite instructions documented here:
and change the following registry value?
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\CA Service Catalog\Version
CA Service Catalog 14.1.05
It is not necessary to make this registry change when upgrading from 14.1.04 to 14.1.05, as catalog does not store this information from 14.1 onward. This registry change mentioned in the documentation is only needed when upgrading from older catalog release levels like 12.9 to 14.1.05.
