Finally...

It took me almost a day to get it to install successfully. With all the prerequisites and carefull planning. I kept getting the “Error 28100.Error loading Event web service”. There are a few suggestions to resolve this, but none of them applied to my situation. It turned out to be an issue with the SQL reporting server. Upon accessing the url's http://localhost/reports and http://localhost/reportserver the following error appeared in the eventviewer:

“It is not possible to run two different versions of ASP.NET in the same IIS process. Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process.”

After configuring the sites to use ASP.NET 2.0, the installation went on to install without additional errors. Now on to the real work.
