Visual Patch (http://www.indigorose.com/products/visual-patch/) is a
program for creating patches (vpatch.exe), for example for upgrading
the version of a program or game to a newer one.

The patch is nothing else than a ZIP archive containing various files
with the "dif" extension that can be a difference file (recognized by
the VISPATCH header at the beginning) or a full file.

All these files are protected by password except one called
_ir_vp2_patchbindata.dat that contains various informations included
the password used for the other files.

Retrieving the password is very simple:
- open _ir_vp2_patchbindata.dat with a text editor (notepad is ok)
- search the string "Check for administrative privileges" (without
  quotes)
- the password is that uid string of the format
  XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX located a couple of lines before
  the searched string

The following example comes from the patch for Burnout Paradise where
the password is 8B0FFA6C-CF99-45F7-BA97-E0AB5C153FAD:

  New Project...Copyright 2009 ....3.0.3.0.3.0.3.0$8B0FFA6C-CF99-45F7-BA97-E0AB5C153FAD.....
  C:\vp_cache....´.................ׂ......Global Functions.ׂ.....
  On Startup˙..--------------------------------------------------------------
  -- Check for administrative privileges

or the following where it's 4C87FE81-ECBF-4779-93C2-21BBDBE39FBA:

  Drawing Board.New Project...Copyright 2009 ....3.0.2.0.3.0.2.0$4C87FE81-ECBF-4779-93C2-21BBDBE39FBA....RC:\Docume...
  On Startup˙i.--------------------------------------------------------------
  -- Check for administrative privileges
  --------------------------------------------------------------

Instead the following one is an example patcher I created with version
3.5.1.0, password 061F2CD6-DB94-4F1E-8F6A-1DE2C4E5CD7C:

  New Project  .Copyright 2010    .3.5.1.0.3.5.1.0$061F2CD6-DB94-4F1E-8F6A-1DE2C4E5CD7C    W
  C:\Documents and Settings\Administrator\My Documents\Visual Patch Projects\cache\shared.   ´   .           . <€.    .Global Functions <€.    
  On Startup˙<.--------------------------------------------------------------
  -- Check for administrative privileges
