Overview:
Adobe LiveCycle document does not render in Vault.
Root Cause:
Adobe LiveCycle files with active fields do not render in Vault.
Solution:
Printing the source file to PDF so that it has no active fields resolves this issue. The Vault documentation contains information about how to re-save a document without the Adobe extension level.
