I have a SQL Server 2005 standard edition installed with a default instance. I need to install an additional named instance. However I could not find the standard edition installer CD; and my colleague managed to dig out a copy of the Express edition installer. Can i use the Express edition?
Installing a named instance using another edition’s installer
Yes you can use the Express edition or you can run again your installer. While you are installing the installer it will ask you if what the name of the instance and after the installation is finished it will ask you to reboot your computer, and then after you installed the express edition you need to reboot again your computer.
Thanks hope this help your problem
