Hi all,
I was having the same issue with the date mismatch and liboog.dll missing.
However, I noticed the same folder setup as posted above. I was also trying to package my project which was located on my F: drive (pen drive) and was sending this to a packaged folder on my C: drive (desktop).
When I moved the project to the desktop and loaded from there and re-packaged, all worked with no issues at all!
Seems a very simple solution so I might have got lucky, but maybe something to try?
