I just ran the installer and right before the DirectX installation prompt, I was told the installer encountered an error and needs to quit. I clicked OK and waited for it to quit. It never quit. It completed the installation and never complained again.

Has anyone else encountered this? Should I reinstall? Might I run into problems later if I don't reinstall?

P.S. I am using CrossOver Games on a Mac so it's possibly just a false alarm but I had to ask all the same.
