Unable to uninstall SQL Server 2008 R2 on Windows 7

0

I'm trying to uninstall SQL Server 2008 R2 on a Windows 7 machine. I keep getting this error message:

C:\Program Files (x86)\Microsoft SQL Server\100\Setup Bootstrap\SQLServer2008R2\x86\sqlcab.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.

That is followed by this:

SQL Server Setup has encountered the following error:
Could not load file or assembly ‘file:///C:\Program Files (x86)\Microsoft SQL Server\100\Setup Bootstrap\SQLServer2008R2\x86\Microsoft.SqlServer.Configuration.SqlServer_ConfigExtension.dll’ or one of its dependencies. This module was expected to contain an assemble manifest.
Error code 0x84B0001

I've tried to reinstall the program but it fails midway through. I've tried to reboot but with no luck either. Any thoughts on how I can completely uninstall SQL Server 2008 so I can re-install it again?

The first file mentioned is probably corrupted, scan and repair you file system, then replace the file(s) with known good ones, then uninstall. – Ƭᴇcʜιᴇ007 – 2014-06-13T20:15:35.620

1try to repair SQL Server first (ru nthe setup again). After you did this, try to remove the SQL Server from Controlpanel->Programs – magicandre1981 – 2014-06-14T07:30:39.487
