I was using SQL Server 7, one months ago. I want to upgrade to SQL server
2000 and uninstall version 7. But now when i install SQL Server MMC, i had
a error message like this:

Unable to save the setup data necessary to maintain or uninstall to application.

İf i disable MMC option when install SQL server, installation succesfull
without error and SQL server run.

I tried both version ; SQL Server 2000 and SQL Server 7

Hardware Configuration:
HP Omnibook XE3
PIII 700
