I needed to install Web Client Software Factory (WCSF) on one old machine which I decided to use for some tests. As far as WCSF needs Enterprise Library 3.1 I’ve decided to install it. And I ran into a problem.

Firstly, let me say what I have installed on the machine. OS - Windows XP SP, VS 2008, Guidance Automation Extensions (GAX) and Guidance Automation Toolkit (GAT) for VS 2008.

So, before to install WCSF I’ve tried to install Enterprise Library 3.1 and I got the error below.

The error says that some types cannot be loaded. That’s why I’ve started fuslogvw.exe from the SDK and tried to see what went wrong.

The last log record has information about the error that has occurred during installation. It was clear from the log that for some reason Microsoft.Practises.RecipeFramework.dll cannot be loaded.

Than what came into my mind was that it is somehow connected with GAT and GAX. Logically, I thought that I have installed newer version of both on my machine and may be it can be the reason. And I’ve tried to uninstall both GAT and GAX. After uninstalling them I’ve tried to install Enterprise Library 3.1 again. And it was installed without any problems.

Have fun!
