Okay, so I have a fresh install of Windows XP 64-bit (using VirtualBox), and I want to install IE-7. Seems simple enough.
Step 1:
I go to the official Microsoft download page and download IE-7 for 64-bit (which seems to be equivalent to IE-7 for Windows Server 2003):

Step 2: I download the exe installation file.
Step 3: I run the installer and it installs IE-7,

...and then prompts me for a restart, so I restart.
Step 4: After restarting, I load up IE from the Start Menu:
and....

...it's still IE-6.
So, what exactly am I doing wrong here? I'm not getting any error, or anything. The installation seems to be successful, but after restart I still have IE-6.
So, what am I doing incorrectly here?
