On running SQL Express installer SQLEXPRWR_x86_ENU.exe this produced a Unhandled Microsoft .NET Framework exception.

If the operating system that Informer is running on is Windows Server 2008 R2 then in Server Manager check under Features that '.NET Framework 3.5.1' is installed


If the operating system is Windows Server 2003, then confirm that Microsoft .NET Framework 3.5 SP1 has been installed under 'Add or Remove Programs' in Control Panel


As per the error message, can either rename the file user.config (or remove altogether).
To rename file, make sure Windows Explorer is set to 'Show hidden files, folders, and drives'
Navigate to path shown in error and rename file.

Note: It is safe to just remove the entire folder 'C:\Users\<windows username>\AppData\Local\Microsoft_Corporation'
