SQL 2005 Express installation error

[bigoldsofty]

I'm still having problems with SQL 2005 Express installations on Windows 7 and Small Business Server 2011, both 64bit. Because the rest of the application is 32bit I have tried it with SQLExpr.exe (WOW install) and SQLExpr32.exe with same result. At the end it reports that the installation 'MAY' have failed.
On checking it has in fact succeeded and also created the instance we require etc.
We have now upgraded to IS 2012 and this still persists.

It is difficult to explain to the client that the error is false in this instance.
How do I get rid of it?

I would look at a couple things..

- Do you have all the correct redistributables installed first?
- Are you doing a project or a suite (if suite look at Detection Condidtion)
- My I ask why you have to use such an old version of SQL (V.S. 2008 r2) on the lastest OS's?

You may need to change the condition of the InstallShield prerequisite. The built-in InstallShield prerequisites for Microsoft SQL Server Express are designed to install the default instance, SQLEXPRESS. If you install a custom instance, you need to customize the InstallShield prerequisite so that it would detect the instance correctly on the target system.
