"the setup has encountered an unexpected error while setting internal properties.  The error is: fatal error during installation"

The initial installation may have been bad but a re-install is not correcting it.

This is the fix (from kb 925976 http://support.microsoft.com/kb/925976)

1. Remove the following registry subkeys that store SID settings:" HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.X\Setup\SQLGroup
" HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.X\Setup\AGTGroup
" HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.X\Setup\FTSGroup  
" HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.X\Setup\ASGroup  
Note In these registry subkeys, MSSQL.X is a placeholder for the corresponding value on a specific system. You can determine MSSQL.X on a specific system by examining the value of the MSSQLSERVER registry entry under the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL\
2. Reinstall the SQL Server 2005 service pack or the SQL Server 2005 hotfix package.
