OK, I’ll add to this. I sent this to Tech Support just now.
OSX 10.13.6, Pro Tools 2018
I get the same error with the updater for EZ Drummer 2.1.4 to 2.1.7. EZ Drummer is on my machine; Pro Tools launches it just fine so it is resent on my machine. I have my EZ Drummer libraries on an external drive and I have an alias in HDD/Libraries/Application Support called EZ Drummer pointing to that external HDD where I keep all of the EZ Drummer and other MIDI drum libraries. EZ Drummer opens them fine. As far as I know EZ Drummer is in the “normal” location; tell me where it should be and I will confirm.
So… how to get PM to update? I also according to the PM have several libraries that need updating; will the PM update them once I get EZ Drummer updated?
