I have the same problem w/ my 3.3.3 install. If you watch the install, it will say Install failed at the end. Then underneath that it will say Installation Complete. Click here to access your portal. Then you get the error above.[EMO]crying.gif[/EMO] I don't why it tells you that the install is complete, when obviously it fails. The install process for DNN is one of the most frustrating experiences in life. Even more so than a tax audit.

I've tried this with version 3.3.4 and same result. If I install 4.3.3, it installs with no problem. Unfortunatley, I cannot use a 4.x version. Could this have anything to do with both frameworks installed on the server? I have DNN in a seperate AppPool, and it is set in IIS to run on v1.1.43222. There are no other applications on this server. HELP
