These two errors are symptoms of the install/upgrade script not finding specific files in the current installation directory or the directory being created newly.

Cause

Files corruptions during download/extraction/edits etc.

Environment

Resolution

1. Rollback to the source version completely (file system and DB)

2. Start the source version and do a sanity check. Preferably also run the Time Slicing job to completion

3. Download and extract the ISO again

4. Make sure that files/folders are not misplaced before or during extraction
