PE-Explorer is an advanced UPX unpacker.
however with the proper user input and scripting it
can be made to unpack themida. (which Engine, and CShell both use.)
But you would be better off manual unpacking
it with Olly, for the reason of writing your own PEExplorer
scripts isn't a walk in the park.
dont google "themida unpacker" because most of
these unpackers are outdated, try to learn some more,
or ask a knowledgeable friend to help.
