Username is the same as Computername

• Error Message: The User Name May Not Be the Same as the Computer Name...
• Installing SQL Server 2008 with user name that equals computer name fails

Regional settings not is same as Windows language type

If Regional settings isn't same as Windows language type SQL server will fail to install.
If Windows is (US) the users Regional settings should also be English (US).
The same goes for other regioanl versions of windows.
FIX: If not set regional settings to same as Windows version install SQL server again.
After installing regional settings can be set back.

A reboot is pending

If something else like a Windows update, ore another program that requires a reboot was installed before SQL server, and scheduled the rest of .dll replacements to happen during next reboot.
Reboot PC before installing SQL server, if it fails, try to reboot again and try once more.
