I have moved the project down to my local machine, built the project and check that everything worked fine, then ran the upgrade, I was then asked for my license username and password. After that I started getting errors.

The first one was in reference to the Bytanium image rotator so I fixed it using the assembly binding redirect method mentioned in the thread for the widget.

The second error was about the version of Telerik.Web.UI assembly. I deleted the .dll and used the one from the previous install. It is now version 2011.1.413.40.

I am now getting a the following error:

How do I go about fixing this? If I try to refresh the page, the error goes away but i get the "your system is restarting" message and it stays on that. It just keeps refreshing but the pages never load.

Thanks.

Edit: I am going from 4.1sp3 to 4.2. I

Hi Anthony,

This error might occur if you have mismatching references for example if you rebuilt the project - this action removes the dlls from the bin folder and results into the exception you were getting.

Could you please check the following articles which contain information which might be helpful to you:

I looked through the bin folders of the blank_project file and that of mine and noticed 4 or so files were missing. I have installed dlls and everything seems to be okay.

Thanks.
