How to check a user's PC for version of Office App

[Stretchcoder]

I am writing a C++ app that is going to add a password to an Office file. I
am not sure that the user of my app will have Office installed (or what
version) on their PC. What is the best way to check before I get into my
automation code?

I assume I could look for a .olb file, but is this the best way to do it?

Thanks!

You could look for certain Registry values:
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Word.Application\CurVer]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Excel.Application\CurVer]
