HUH. Salted please email cfsup@adobe.com and let them know the details on this. Meaning, let them know that the installer showed errors on your CF2018. They should be able to let you know how to check that the update completed successfully. I believe it may be a known bug that some "warning" messages that do not have actual deleterious effects on the install are displaying when they should be suppressed. This is occurring on 21 and 23 though, this is the first I heard of it on 2018...

@Mark Takata (Adobe) it would be great to have a document that tells us what warnings/information can be ignored here and there. I'd have to search for examples, but there seem to be so many "I think this is expected" log entries when searching for issues, but don't really have time to do a full blown investigation.

Chris, definitely noted, and I think the real answer there is that on our end we need to suppress those messages, and fix issues that cause confusion. The more "exceptions" in the wild, the better the chance that customers will be confused.

Much appreciated
