After installing Office 2008, there were three critical updates, each
seemingly replacing the previous. I believe they were 12.1.0 then
12.1.1 then 12.1.2. They were all about 150 MB in size. It's too bad
Microsoft doesn't offer a single cumulative update. Having to install
three critical updates right after installing a program doesn't
instill confidence. Furthermore, most users wouldn't think to perform
an update.
