I have Acrobat DC 2017.009.20044 and now the almost all of the Preflight PDF standards compliance checks seem to have disappeared. I now have an extremely reduced set of profiles. The only visible "PDF/A compliance" profiles are "Convert to PDF/A-1a" & "Convert to PDF/A-1b".
I can edit the Preflight profiles and create custom profiles for my requirements but it seems rather inconvenient I should have to do this?
Has anybody else experienced this?
The profiles, checks and fixups in Preflight have been partitioned into libraries in the latest release of Acrobat Pro/Preflight (April 2017).
By default the library "Essentials" is shown, which indeed contains a relatively small set of profiles/checks/fixups.
If you switch from "Essential" (by clicking on the popup menu at the top of the Preflight window) to "PDF standards" you will find all of the profiles related to checking the various PDF standards (and also profiles to convert PDF files so they become conforming with a chosen standard).
If you had a previous version of Acrobat Pro / Preflight installed, you will also find all your previous profiles, checks, and fixups (including those you may have modified, created or imported yourself) in the library called "Acrobat Pro DC 2015 Profiles".
Yes, there they are!
