Excel 2010 Component Id

[gurry]

Hi,

We have an Excel plug-in written back in the day for Excel 2000. Now
we're trying to port it to Excel 2010. So we need to add an Excel 2010
pre-requisite in its installer's Launch Conditions.

For this we must have the component id of Excel 2010 installation.
However, I can't find that anywhere on the Internet. Could someone
please point me to the right location?

I did come across Excel 2010 PIA's component ID. But to add a pre-
requisite for the PIA wouldn't work for me. That's because, being as
old as it is, our plug-in's code doesn't use any PIA's (it lets Visual
Studio create all the Interops).

Also, the component ID's for previous Office versions are easily
found:

Why has this changed for Office 2010? Am I missing something?

Thanks in advance.

Found the component ID myself by snooping around in the registry. It
is 538F6C89-2AD5-4006-8154-C6670774E980 and its location is
'HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Common\Licensing'.
