Setup initialization error: Source \SQL2000_SP3a\x86\Setup\Sqlspre.ini.

Cause:  You may receive this error when you try to install SQL Server 2000 Service Pack 3. It occurs when the Service Pack 3 Setup program tries to copy Setupsql.ini to the %Temp% folder, but cannot overwrite a pre-existing version of the file that is marked as read-only.

Solution:  Browse to the %Temp% folder on your system drive, and either delete the pre-existing version of setupsql.ini or remove the read-only attribute. Then run SQL Server 2000 Service Pack 3 Setup again.
