Error Message After Rebooting and restarting VS.NET

Hi folks,

After the Installation of the Patch 3, it works well within VS.NET, but when I shutdown my pc, and restart it the next day, I allways get the following error message when I start VS.NET 2003:

The Add-in "Portal Development Kit 1.0 Patch 3 for Microsoft.NET" failed to load or caused an exception. Woul you like to remove this Add-in?

If you choose yes, you will need to reinstall the Add-in to use it again.

Error Message: Class not registered

Error number: 80040154

Any suggestions?

    Hi Johannes,

    Which version of VS 2003 you are using?

    this message can be accurse when you are installing the PDK for .NET on Visual Studio .NET Academic Student Tools 2003.

    Please look at the "Installation, Upgrade and Configuration Guide - PDK for .NET" guide.

    Any way if you are using VS 2003 professional and above I suggest you to remove the program and install it again.

    You can download the supporting guides from for .net administrator

      Thanks again
