Details: UIUPrep now logs to \ProgramData\UIU\UIU.cmtl.log in addition to the standard UIUPrep log file, in Configuration Manager Trace Log (CMTL) format.This log is a duplication of the standard UIU log while migration to CMTL format is in progress.
Symptoms: Servicing older Windows PE media (3.x & 4.x) requires 32-bit specific binaries (DISM) which do not load under a 64-bit process, resulting in error conditions. Big Bang recommends that Windows PE version 10 be employed. Contact UIU Support for additional information.
