Microsoft SQL Server 2005 Express edition is already installed. I added SQL Server 2012 Express in Prerequisite in Windows Installer.

I'm getting this error while installing setup at start

Can not install different instance. Required instance name as SQLEXPRESS.

Prerequisite check for system component SQL Server 2012 Express failed with the following error message:
"SQL Server 2012 Express (x64) cannot upgrade the existing instance of SQL Server Express (x64 WoW) named 'SQLEXPRESS'.
Uninstall this instance of SQL Server Express and retry installing SQL Server 2012 Express (x64)."

Thanks

You try to give the name SQLEXPRESS to your second instance while there is already one (2005) instance on this pc with the same instance name.

What you need is just to give another name to the second instanse, for example SQLEXPRESS_2012, when install it

  • But I want instance name as SQLEXPRESS not SQLEXPRESS_2012. Is it not possible to upgrade? – Dev Sep 15 '17 at 05:18
  • If you want to upgrade, just upgrade it, not install the second instance. – sepupic Sep 15 '17 at 05:22
  • >>>after upgrade also its giving same error<<< What does it mean "after"? The instance has been upgraded or not? And what is your full @@version of existing instance? – sepupic Sep 15 '17 at 06:17
  • @Dev, please update your question with the result of SELECT @@VERSION on your existing instance. (x64 WoW) makes me think you are trying to upgrade x32 to x64 that is not possible – sepupic Sep 15 '17 at 06:29
  • I have created instance with different , solved problem thanks – Dev Oct 16 '17 at 12:34
