SQL Server 2008 unattached installation setting IACCEPTSQLSERVERLICENSETERMS not recognized

I am trying to install SQL Server 2008 Express but I always get this error:

SQL Server Setup has encountered the following error:

The setting 'IACCEPTSQLSERVERLICENSETERMS' specified is not recognized.

Error code 0x84B40003.

My code is here:

Looking at the documentation page, and this blog posting, I don't see why what you're doing doesn't work, but I can suggest two things to try:

1. Change the case to be IAcceptSQLServerLicenseTerms instead of all caps. I doubt that matters, but it is a difference between your code and what is on these two pages.
2. Delete that one parameter from the configuration file and add it to the command line arguments, so that

This line:

process.StartInfo.Arguments = "/SAPWD=""" & saPassword & """ /CONFIGURATIONFILE=""" & configFileName & """"

reads as:

process.StartInfo.Arguments = "/IAcceptSQLServerLicenseTerms /SAPWD=""" & saPassword & """ /CONFIGURATIONFILE=""" & configFileName & """"

instead.

I had this same problem myself recently.

The issue is that the /IAcceptSQLServerLicenseTerms option was added in 2008 R2, and so is not available in SQL Server 2008. I just removed the option, but using R2 instead should fix the problem too.
