I was trying to run the preflight tool on one of my pdfs and its giving me the same error "Unknown error (unknown exception)" for all of the options in the PDF analysis and PDF compliance tabs. What's going on?

At my company we are also seeing this error.

We first noticed it when we were upgading from CS6/ AcrobatX Pro on Windows 7 to CC/ Acrobat DC Pro on Windows 10.

We noticed that:

A PDF created with CC/DC/Win10 showed this error when preflight was attempted, but, the same PDF file preflighted fine on the CS6/X/Win7.
A PDF created using CS6/X/Win7 preflighted OK on both systems.

We are continuing to use CS6/X/Win7 for preflighting and hoping for a resolution soon.

This makes me think that the error does not seem to be a part of the PDF file itself or the Acrobat preflight tool.

Is staff looking into this as an Acrobat DC interaction with the OS?

Is staff seeing this error on MAC OS also?
