This should clarify the situation:
Q: Can I download/install additional patches?
A: Yes, you can adjust how the download and update scripts behave by excluding or adding patches from download or installation. For adding updates proceed as follows:
1. Adding updates to download routines
For adding an update to be downloaded, insert its download URL into the matching "StaticDownloadLinks-<platform>[-architecture>]-<language>.txt file, found in the "...\static\custom" directory. Please don't forget a trailing <CR><LF>.
2. Adding updates to installation routines
Add an update to installation by inserting its knowledge base ID (KBxxxxxx or simply xxxxxx) into the matching "StaticUpdateIds-<platform>[-<architecture>].txt file (directory "...\client\static\custom"). Please don't forget a trailing <CR><LF>.
Q: Can I skip the dynamic update determination during downloading/installation in order to use my static definitions only?
A: Yes.
To avoid dynamic update URL determination during download, add "skipdynamic=Enabled" to the [Miscellaneous] section of your UpdateGenerator.ini file.
To avoid dynamic update ID determination during installation, set "skipdynamic=Enabled" in the [Installation] section of your UpdateInstaller.ini file.
