Hello,

I downloaded the upgrade package of DNN 8.0.0. I followed the procedure about DNN upgrading and I copied all extracted files from ZIP over a copy on my website.

But when I put in my browser the url http://mysite/install/install.aspx?mode=upgrade I obtained the following error: Could not load file or assembly 'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. 

I checked and Newtonsoft.Json.dll exists in "bin" folder. The version of this DLL is 7.0.1.18622. 

So, I changed my web.config and I typed the following script:

<dependentAssembly xmlns="urn:schemas-microsoft-com:asm.v1">

        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />

        <bindingRedirect oldVersion="4.5.0.0" newVersion="7.0.1.18622" />

</dependentAssembly>

But the problem is still present.

My environment is the following: IIS 7 on Windows 2008 R2 server.

Where is the problem?

Thanks.

Massimo

I had one heck of a time trying to get past this.  Took quite a few backups and restores before I finally got it right.  From what I could tell, there are some older modules that just simply bugger things up when you try to upgrade to 8.0.0 with conflicting versions of Newtonsoft.Json.dll.  Unfortunately I don't remember exactly which ones they were.  But by making backups of my database and dnn application folder, deleting unused modules, I was eventually able to get DNN to upgrade successfully.  Hopefully someone here can post a list of exactly which modules cause the problems.
