Acrobat 11 fails to start

Have Acrobat 11.0.14 and Reader 11.0.14 installed on Windows 7 64bit (with all updates as of today), and Reader works.  When you launch Acrobat (as either a normal user or with admin rights) it cycles constantly - the cursor flashes, changes to the spinning cursor, goes back, you lose the ability to control anything every few seconds, and if you open taskmanager, you see acrobat.exe appear for a second and then go away, and it does this until you either reboot or are quick enough to catch it and cancel.  Distiller does the same thing.  I've used the cleaner to remove it and reader and reinstall, this did not help.  This system also has AutoCAD 2016 installed if that matters, but I have other workstations with the same windows 7 image and autocad and this install of acrobat works with no issue.  I don't see any errors and nothing in the event logs that help.
