Last three registry settings for acrobat preferences

Hi,

I've just about completed Acrobat DC installation with the Customization Wizard, making new entries in the Registry or utilizing the Edit Preferences, and copying these to the HKCU or HKLM as appropriate.

I am stuck on these three areas:

1) in AVConversionFromPDF I want to change the "Primary OCR Language"  for Word. This wasn't picked up by the entries in cSettings

2) Color Management: here I'd like Settings: Europe General Purpose 3 as default.

3) in Multimedia Trust (legacy) I want to select all three playback options

Many thanks  in advance for any pointers or advice.
