1. Is the Interop.ACRODISTXLIB.dll library still being distributed with the current version of Acrobat? (This permits programmatic distillation.)
2. Is it being distributed under a new assembly name? (Have not found any references to it beyond 2010.)
3. If it still exists, does the Acrobat installation make it immediately ready for COM-referencing within a C# application?
Sorry, I found it. It is provided as the distiller COM reference within Visual Studio after AcrobatDC has been installed. Look for "distiller" in the COM references instead of "Interop.ACRODISTXLIB".
