A few weeks ago, I posted an entry describing a scenario where you may encounter package load failure error dialogs for the Class Designer Package while using the Visual Studio 2005 IDE after uninstalling VS 2005 beta 2 in an incorrect order and then installing a later CTP or the release candidate build. Since then I've had a few people contact me who had trouble getting the steps that I posted in that previous post to work, so I wanted to post a more straightforward set of steps that didn't require installing Orca and navigating through the VS MSI.
If you are running into this issue, I would first encourage you to download and use the updated version of the VS 2005 cleanup tool, which will automate cleaning up the files that cause this package load failure. Please note that this tool is only designed to help solve issues caused by previous beta versions of VS 2005 that were installed on your system. If you have not ever had a beta of VS 2005 on your system, this tool will likely not help you.
If you would prefer to clean it up manually, here are some more straightforward steps that will allow you to do so. Note that these steps assume that the machine has previously had VS 2005 beta 2 installed and that it was uninstalled in an incorrect order (meaning the order of uninstall listed here was not followed exactly). It also assumes that the machine has a later build of VS 2005 already installed.
Note that I have inserted spaces into some of the commands above to force it to word wrap on the blog site. If you copy and paste these steps please remove the spaces before running the commands listed above.
