Windows 7 and Canon Utilities

After my modest success with installing Windows 7 on my home computer, I spent my Monday morning at work installing Windows 7 there. Because I sometimes use my Canon camera at work, I brought in the software CD for EOS utilities.
When I tried installing the software, however, I encountered a dialog that said "Installation program of EOS utility requires administrator privileges." The problem was that I am the admin on this machine! I don't know what that difference is between my home and work environments that would cause this to happen. I tried the "run as administrator" command, and I tried compatibility modes.
When I googled the error message, I got one hit: http://photography-on-the.net/forum/showthread.php?p=9162655. The solution, which worked, by the way, is a doozy. Get a load of this:

1. When you receive the error , DON'T click the "OK" button.
2. Navigate to the following path: "C:\Users\admin-user\AppData\Local\Temp\".
3. Inside this directory, you should see a directory named something like "CanonUPW_000". Copy this whole directory to another location.
4. Then click "OK" on the installation program error on the screen (which removes the directory you just copied).
5. Open the directory that you copied in the last step and navigate to the following location: ".\CanonUPW_000\INST\INSTALL\COMMON". You should find an "Install.exe" file in this directory.
6. Open the properties of this "Install.exe" file, then select the "Compatibility" tab.
7. Select the "Change settings for all users" button and select the "Run this program in compatibility mode for "Windows XP (Service Pack 3).
8. Under the "Privilege Level" section, select the "Run this program as an administrator", then click OK twice.
9. Execute the "Install.exe" file. The installation should start and finish successfully.

Great googly moogly!
