This is another recommendation about this issue from one of our partners @ Ottoboni Group Kalle Ljung. I have done these steps myself and have no trouble today between Vista and EPiServer. :) 1. Install .NET Framework 1.1 2. In the Control Panel, Programs & Features, install: - IIS 6 Management Compatibility - IIS 6 Management ConsoleIIS 6 Metabase and - IIS 6 configuration compatibility 3. Make sure the site runs .NET 2.0 after the install of .NET 1.1 4. Install EPiServer Manager 5. Shut down User Account Control (UAC), otherwise you get Access denied when you list the websites. 6. Install EPiServer with .NET 2.0 templates according to the instruction on www.episerver.com 7. Point 404 side to /Util/NotFound.aspx and change "Error Responses" to "Custom errorpages" under "Edit Feature Settings...", these settings are not found under "Error Pages" for the EPiServer website. 8. Make sure that the site uses "Classic .NET AppPool", if this does not exist, create a new application pool wiht settings: .NET Framework version: 2.0, Manged pipline mode: Classic When I tried EPiServer i Manged pipline mode: Integrated så började w3wp.exe process started loading the CPU 100%. It seems that IIS does not handle URL with + chars, this means that the tree in Edit shows wrong pictures that refers to: Util/images/ExplorerTree/T+.gif A problem is that they have changed the handling of error pages in IIS7 ad to get "FriendlyURL" to work you need to turn on the errorhandling even if you run it locally. This means that you DON´T se the error message generated from .NET but a ”nicer” page. So the solution is not to use FriendlyURL when you develop. Case:75325 I actually solved the issue with the + in url. I had to do some system changes by inserting In C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\web.config just before according to http://support.microsoft.com/kb/927672 I also solved another issue with system stylesheet for edit and admin. When this is browsed the browser does not the .css. It tries to load a /Util/styles/system.css. This does not exist so I created a copy of system_template.css and it worked like a charme.

I would suggest against disabling UAC, especially since it does not seem to interfere with EPiServer operations at any time later. Instead open your Episerver Manager folder (probably C:\Program Files\EPiServer Manager) and in the file property of EPiServerManager.exe set it's privilege level to run as administrator.
