To change an existing instance of Microsoft SQL Server 2005 to a different edition of SQL Server 2005,
you must run SQL Server 2005 Setup from the command prompt and include the SKUUPGRADE=1 parameter.

This error , I am have seen in the logs.

The installation wizard is closing down with the above log error.

ThanksSounds like you have a previous install on there. I would check to see if you can uninstall the previous version, then re-install the version you want. Either that, or find the CDs from the original install.|||I have tried to uninstall and re-install everything , but still I am struck.

The log file shows:
