[wpkg-users] Condition logic

[Paul McGrath]

Hi,
  Just looking for advice on whether I can make this simpler.  The aim is to install the correct bit version of Visio or Project for the corresponding bit version of Office 2013 that is already installed.  If Office 2013 is not installed then install the bit version that matches Windows 7 e.g. W764 = X64 version of Visio/Project.
  I've research the bitness versus product code and after Office is uninstalled the product code values still exist.  Bitness is more reliable but I am sure not 100% fool proof.
This I what I have come up with:

     <package id='visio' revision='1'>
      <!-- CHECK IF W732 & OFFICE2013 32BIT ALREADY INSTALLED -->
      <install architecture='x86' cmd='download.exe visio2013x32bit.zip'>

           <check type='logical' condition='and'>

              <check type='logical' condition='or'>

                 <check type="uninstall" condition="exists" path="Microsoft Office Professional 2013" />
