MBD - Adobe Reader DC 64 bit version not working correctly

[zmiller]

Hello All,

For those doing MBD and using 3D PDFs have you ran into problems using the 64 bit version of Adobe Reader DC?  We've found that PMI reference highlighting is not working when PDFs are opened with 64 bit Adobe Reader DC, the 32 bit version works fine.  To make the problem worse we are seeing that 32 bit installations are being automatically upgraded to 64 bit by Adobe.

We've been working with our 3D PDF creation software vendor and have come to the conclusion that there is a major regression in Adobe functionality with the 64 bit version.  There are at least two open requests to Adobe to fix this, see links below.  I'm interested in knowing if others are having the same problem.  Also if you could vote for the Adobe issues maybe this will get fixed.
