On a 64-bit windows you should get the DisplayVersion key under:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{AA7699FA-B2D2-43F4-8A70-D497D03C9485}_is1]

And on a 32-bit windows you should get the new DisplayVersion registry key under:
Windows Registry Editor Version 5.00

Just looked the Inno setup iss file over once more and find the following line odd:

AppID={{AA7699FA-B2D2-43F4-8A70-D497D03C9485}

I owudl have thought that line should be:
AppID={AA7699FA-B2D2-43F4-8A70-D497D03C9485}

i.e. without the doubled-up leading opening curly brace? But hey it used to work, so maybe that double curly brace was OK?

This patch adds the required lines to the Inno setup "iss" file, to cause the software version number to make it into the windows registry uninstall key for openLP.
