I went through all the installation instructions for DNN version 3.1.0. I checked The database and all related Db Objects installed fine. Once, "Installation Complete" appears, I click on the "Access Your Portal..." and I get the following compile error from the DNN site. Any ideas?

Object reference not set to an instance of an object.

I also am getting this error after re-downloading the 3.2 release from two different download sites and installing it multiple times.
I am glad I am not alone.
Anyone else having this issue? Anyone else performing an upgrade and having it work as expected?

Same here. I looked at everything including bugs already verified, folder permissionsa, etc. but could not resolve it.

Either the resolution to this problem is very obvious and we are blind, or noone seems to have any ideas. I have looked back at previous postings with the same error message and also found a couple with DNN4.0. Some have received it due to web.config issues, installing with incorrect db owner, etc. I check all in my environment and none applies. I am baffled.

Looks like we are all in the same boat. Upgraded to 3.2 from 3.0.13 and followed the instructions in the Install Docs.

Received this error:

I occasionally get this error. But when the page is reloaded, the error went away.

I found this article.. which displays exactly same error message, but this solution will probably not work for those who have not installed that specific

Have you tried recycling IIS / or rebooting the server (if you have access to do so)? Also try clearing your cache and closing all browser windows to make sure absolutely nothing is cached.

At the risk of being plain stupid here... This is a MS knowledgebase article dealing with this issue...

Thanks for the link. I did, in fact, see that KB article but dismissed it because Ididn't feel it applied to my particular situation. My dev server has both the SDK and VS.NET installed, but maybe I still need to register the dll.

Those experiencing this on a remote host may have some difficulty getting their provider to make changes to their systems, I would think?

This error is often remedied by touching the web.config, so dotNet recycles the application. You can also try resarting IIS.

Good Luck.
