What version (including what Update) are you currently using using and what Update are you trying to install?

Answer 1

[Walter Roberson]

You tried to install a r2019a release update but you are not running r2019a.

Release updates are bug fixes for a release. They do not upgrade a previous major version to a newer version.

[John McCaleb]

no, I'm definitely installing 2018b update 4

[Walter Roberson]

Ah. Though I notice the directory name is R2018b_Update_3 ?

Also I wonder if you just happen to have R2018b Update 1 ? That one corrupted installations.
