find Office version for setup program

[Jantje]

I like to install one of two programs on my client machine dependent on the office version. For that I use the Inno setup Program.How can I get that . The number for office 2007 =12 and for Office2010 is 14

Based on that the setup program can install the right program.

#if Office version <=12 then

install program1

#else install program2

#end

There is a version number in the registry, in this location:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\
