Application: WebMatrix.exe

Cause: You did not use Microsoft Web Platform Installer for direct installation, and many dependencies are missing for self-installation.

Different Versions of WebMatrix3 depend on different components. Download the Microsoft Web Platform V5.0

The following components need to be installed: (64-bit system is used as an example. 32-bit systems do not need components labeled x64)

Microsoft SQL Server 2012 Transact-SQL ScriptDom

Microsoft SQL Server 2012 Data-Tier Application Framework 11.0x86 (December April 2012)

Microsoft SQL Server 2012 Data-Tier Application Framework 11.0x64 (December April 2012)

Microsoft WebMatrix 3

Microsoft System CLR Types for Microsoft SQL Server 2012 (x64)

Microsoft System CLR Types for Microsoft SQL Server 2012 (x86)

Web Deploy 3.0-July 2012

You can search for and install these components from the Microsoft download center, or install visual studio express 2012/2013 directly.

These components are shared with visual studio express 2012/2013 or sqlserver 2012 express.
