Office 2016 and Acrobat DC not working together

I have Office 2016 and installed and activated Acrobat DC (no errors).

Trying to get MS and Acrobat to work but constantly fails.

Open an Excel spreadsheet, and try and use the Acrobat plugin - Excel crashes - when trying to create a PDF from within  a spreadsheet- "Microsoft Excel has stopped working..Restart program."

I've tried the same from WORD, and get exactly the same error (MS Word has stopped working...)

Opening Acrobat first, and then using 'Create from File' and choose an Excel file:

I get Missing "PDFMaker files - Do you want ti run the installer in repair mode?"

Naturally, I've clicked YES (many times), and it does something (please wait while Windows configures Adobe Acrobat DC...), but at the end, nothing changes, still get same error each time I try and create a pdf.

Any ideas? Do I need to try and re-install Acrobat? Will that help as it seems to be installed correctly already (works on its own, it's just the MS integration that is failing)

any help appreciated
