When trying to convert to PDF within Opus *(from, say, a Word file) - right click "Convert to Adobe PDF", I am getting an error reading - "Missing PDFMaker files. Do you want to run the installer in repair mode?"
This has previously been working.
I did try to "run the installer in repair mode", but after about quarter of an hour of little or no progress, I gave up.
Adobe Acrobat version 9 is installed and working fine.
Just ran an experiment on my spare machine, which still has Acrobat.
Conversion went just fine from within DOpus.
Your best bet would be to launch Acrobat and check that it is working as expected in its own right. The start worrying about how it integrates with other software.
If it works OK, then see if it plays nicely with Word. The right-click conversion launches Word.
In other words, work your way up the chain of command.
