How to reinstall SCE07 on EBS 2008

Hi All

I am having a unfathomable degree of trouble with an SCE 2007 reinstall on the Management server of EBS 2008.

I have read in places that it is designed not to be uninstallable, and in others that people uninstall betas etc, to install the full version. In any case here is what happened.

Uninstalled SCE 2007 as we messed up WSUS and couldn't see another way to uninstall only that portion.

The uninstall of SCE07 went something like this:

1. Click uninstall
2. Confirm
3. ERROR CAN'T UNINSTALL

However, upon reboot, SCE07 is gone, HALF of wsus is gone, HALF of the SQL Express it ran on is gone. None have left behind uninstallers or anything. By half i mean, SCE's installation wizard detects all of its subcompents as still installed, but the majority of files, registry keys, and the some of the uninstallers in Programs & Features are gone.

I have gotten WSUS uninstalled manually and now pass this check in the SCE07 installer, the massive problem i am having is SQL.

Trying to reinstall SCE 2007, i reach the SQL configuration screen, where there are 3 options.

1. Install using SQL Express on this server
2. Install using an existing SQL installation on this server
3. Install using an existing SQL installation on another server.

it says 2 & 3 require SQL Reporting services to be installed and configured on the Management server where SCE is being installed.

So, after much googling, and attempting to follow manual SQL unisntall proceedures, all 3 options are stilled greyed out. I am too scared to fully uninstall all SQL related things (ie, delete all related registry keys en-masse) for fear of damaging the Windows Internal Database. So the following items are still installed:

SQL Server Native Client
SQL Server Setup Support Files

If you run the Bootstrapper to uninstall SQL, it still lists the SCE instance as uninstallable, always did. The SQL Configuration tool does not show this instance as installed.

So i arrive at a Junction:

Option 1: Warning: Installing SQL Server 2005 Express is not supported on this architecture.
Am i correct in assuming this is because its detecting another instance of SQL Express, and SQL Express doesn't support multiple instances? I Am using a SCE 07 standard disc, maybe i should find the installer that is packaged into EBS somehow?

Option 2 is unfavourable, as we dont have a license to install SQL Server 2005 or 2008 onto Management server directly.

Option 3 requires Reporting services to be installed, which we cannot get to install either.

So, I am hoping for some advice on how to fix this massive mess. Ideally we want to regain the ability to use Option 1, installing SCE onto management server using the prepackaged SQL Express.

Is the SCE installation that comes packaged with EBS2008 available on the install disc somewhere? I cant find it.

I hope my post makes sense, but it probably doesn't as i've been beating my head against the wall on this for 4 days straight and a coherrent idea of where i'm at is not plausible with my current state of mind.

Any advice would be fantastic, and i will be eternally grateful.

Thanks, Charles
