Assuming you're playing Halo PC, go to your C drive in My Computer. Navigate to the following directory: C:\Program Files\Microsoft Games\Halo\
You should find a file called msxmlenu.msi.
Double click on that and let it install.
Problem should be fixed.
If you're playing Halo Custom Edition, the msxmlenu.msi file is simply one directory deeper, in ...\Halo Custom Edition\Redist
If you don't know what Halo Custom Edition is, check the link in my sig out. It's a free new version of Halo. :)
