Installing SQL Server 2000 after 2005

I use SQL Server 2005 (Express); I have a client now that uses 2000 and to support this client, I need to install SQL Server 2000 Enterprise Edition on the same pc.  Can I do this?  Any advice is greatly appreciated - I don't want to try it until I'm pretty sure I won't mess up the 2005 version!

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

yes, you can install both versions of sql 2000 and sql 2005 on the same machine.
just make sure you get different instance names.

However: if you wish to change yourPCname\anythignwhatyoutype to default yourPCname
you need reinstall sql server

Also you can run your client's SQL 2K database inside SQL 2005 using "SQL Server 2000 Compatibility Mode"
This way you will not waste your resources by running two different version of SQL Server.
You will find alot about it in he MSSQL Online Books
