Design a MOSS 2007 workflow locally

After installing Microsoft Office Sharepoint Designer (MOSD) 2007 on my client I tried to create a workflow on a remote Microsoft Office Sharepoint Server (MOSS) 2007 server. I connected to the Sharepoint server using MOSD but when I tried to create a workflow I got the error message 'The list of workflow actions on the server references an assembly that does not exist. Some actions will not be available. The assembley strong name is Microsoft.SharePoint.WorkflowActions, Version=12.0.0.0, Culture=neutral, PublickeyToken=71e9bce111e9429c. Please contact your server administrator.' .

Using the Sysinternals Filemon tool, I discovered MOSD was looking for that assembly on the local machine (and not on the server as stated in the error message). I copied the assembly from the GAC of the server to my local GAC, and that error was gone.
However, I could not create a new workflow: 'Failed to load the workflow'.

I did install some other Office 2007 products so installed the Technical Refresh for beta 2. Big mistake! The menu-items of MOSD were completely screwed up...

I tried removing, reinstalling, cleaning the registry, cleaning the filesystem, reinstalling, ... no luck however. So I decided to restore my system to the restoration point I created before installing MOSD.

In the meantime I had stumbled upon a page starring a technical refresh for MOSD only. I reinstalled MOSD (I did not reinstall any other Office component) and ran the technical refresh on this product. And now I'm about to create my first workflow using MOSD ;-)
