Article ID: 2292664 - View products that this article applies to.

SYMPTOMS

You install one version of Visual Studio such as Visual Studio Express (VB, C# or Web) and then patched it to Service Pack 1. At a subsequent time you install another version such as Visual Studio 2008 Standard or Professional edition but do not re-install the service pack.

When you launch Visual Studio you may get package load failures such as the following:

Package Load Failure

Example:

Package 'Microsoft.VisualStudio.Xaml' has failed to load properly ( GUID = {E58C2A8B-BCC4-4559-AD59-D62EB6D58A22} ). Please contact package vendor for assistance. Application restart is recommended, due to possible environment corruption. Would you like to disable loading this package in the future? You may use 'devenv /resetskippkgs' to re-enable package loading

CAUSE

The different versions of Visual Studio need to be at the same service pack level.

RESOLUTION

To fix the problem, you can run the standalone Visual Studio 2008 Service Pack 1 installer. This should leave both the Express SKU and the Standard SKU with a working WPF designer, service packed to SP1.
