deploying a winform application using clickonce and iis fails

Question

I'm trying to deploy a winform application with IIS and ClickOnce. I can access the publish.htm page and the install even starts when I click on the provided link. However I get this error during the installation process:

• Downloading http://MyWebSiteUrl/.../Interop.SHDocVw.dll did not succceed.
• The remote server returned an error: (500) Internal Server Error.

Can anybody help me out on this ?

Thanks, Bruno
