    App_Browsers error installing umbrao 4.5

    Hi everyone,

    I'm getting this error: "Could not load file or assembly 'App_Browsers' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded." when installing Umbraco on win2008 server/IIS 7.0 environment using the .net 3.5 web.config file.

    Any Ideas?

    Is this an upgrade or a fresh install?

    Fresh install.

    Yeah, the new version seems to be targetted to 4.0. So you'll need to install the framework 4.0 (if you haven't already), allow it as web service extension in IIS, configure your site to use it, and make sure it's in an app pool that only has other 4.0 sites (can't mix frameworks). You may need to recycle your app pool or restart IIS to get all the above working.

    Edit: Just noticed it was a fresh install, so the following doesn't apply - There are new config files to copy over, and your web.config will probably need a refresh. Once all that's done, you *should* be good to go. At least, I can't remember any other steps.

    I haven't been able to upgrade 100% successfully yet (admin console is missing the tree), but installing fresh seems fine.

    Well, thanks for the info, although I find targeting 4.0 is a bit of an early step considering current hosting options.

    Also I wonder, if .net 4.0 is alrea dy targeted, why do I have to change config files, shouldn't they be included in the installation already. 

    Edit: Now saw your edit.
