Release : 17.3 RU6 and higher
Component : XFLOW INTERFACE FOR SDM
The JRE directory is missing and had failed to be created. The installer may be failing as there may be UAC (User Account Control) in place and is restricting access to the "C:\Program Files\CA\SC" and "C:\Program Files (x86)\CA\SC" locations.
Before performing the following, please make sure there is a backup of the installation in place. Ideally, if there is a snapshot of the environment prior to installing the RU, please rollback to the given snapshot first.
The following instructions are applicable for a 17.3 RU8 configuration which introduces JRE 11.0.3. The instructions should also apply for 17.4 releases where SearchServer install update experiences a fault for the same reasons described here. This JRE release will vary depending on the RU in question.
Activity was performed on the dedicated Search Server server.
Other steps taken which resulted in successful upgrade:
elasticsearch.yml had blank fields where the host name should be
config.yml had a blank locale which was updated to English.
