Office 2010 hase corrupted Office 2007

[Michal]

Didn't like Office 2010 so uninstalled them but now getting error that
MSO2007 hasn't been installed.
I have a Windows Vista Ultimate, but I wasn't able to find installation for
office from my dvd.

How do I install them from my vista ultimate dvd?

You require an Office cd in order to install it, Office is not on the Vista
dvd
