  • Error when installing

    • I get "The extension manifest is invalid" when I try to install the T4 editor.

      Here's a part of the installation log:

      2009-10-21 18:08:35 - Beginning to install extension to Microsoft Visual Studio 2010 Ultimate...
      2009-10-21 18:08:35 - Install Error : Microsoft.VisualStudio.ExtensionManager.InvalidExtensionManifestException: The extension manifest is invalid. ---> System.InvalidOperationException: There is an error in XML document (2, 2). ---> System.Xml.Schema.XmlSchemaValidationException: The 'http://schemas.microsoft.com/developer/vsx-schema/2010:VSIX' element is not declared.

      at System.Xml.Schema.XmlSchemaValidator.ValidateElement(String localName, String namespaceUri, XmlSchemaInfo schemaInfo, String xsiType, String xsiNil, String xsiSchemaLocation, String xsiNoNamespaceSchemaLocation)
    • It works now!

      If you've had the editor installed before (in Beta 1 for instance) you need to remove the AppData directory:
      C:\Users\<username>\AppData\Local\Microsoft\VisualStudio\10.0\Extensions\tangible engineering
      That's all, then it works "as advertised".
