Yes, that is normal if your client is too old.
Updated to 2.4.7, undoes settings removal in 2.4.5, improves performance and stability, and adds support for idRO (region-locked). There is also some more stuff to read in the doc/ folder.
Updated to 2.4.8, adds support for ASLR and DEP, improves kRO mirror balancing and the GRF repacking scenario.
Updated to 2.4.9, fixes, among others, some elevation-related issues.
Updated to 2.4.10, fixes mirror selection issues and adds an option to always patch from kRO mirrors.
For the time being this is probably the last update to RO Patcher Lite before ELUR is released.
