Failed to load receiver assembly exception occurs when activating the wsp file

Question

I have a sandbox solution, that is created from VS2010. The sandbox was actually created for SharePoint 2010. The sandbox solution also works smoothly in Office 365 (ie SharePoint 2013 Online ). When it is activated, it will add a library and add a web part page inside of that library. But when I tried to activate the same sandbox solution in the SharePoint 2013 Server (On-premises version, which is installed locally in our server machine), I got the following error as seen from FUSLOGVW.

*** Assembly Binder Log Entry  (6/16/2013 @ 2:55:20 PM) ***

The operation failed.

So I was wondering why the sandbox solution works in Cloud version of SharePoint 2013 but does not work in On-premises version. Can someone shed some light on it? I have tried to activate the sandbox solution using the Browser. I have not tried using the power shell. Will it make any difference?

Thanks,

I'm in the same case; App developped via Nappa, deploy and works on sharePoint Online (the one bundled with Office 365 account).

When I want to install it on our SP 2013 local server (via PowerShell) it exit during the "Installing" status, and in the log i got the famous: " Missing one or more of the following attributes from the root node in solution SOLUTION_NAME.wsp : assembly '', type ''. "

This error is wide meaning, as it can come from differences between SP versions, variables types used, bad manifest file, WebConfiguration ...

In my case I didn't found out where it can come from yet. My app is very simple, it only load a list content, and display it in a particular manner by using pure web (HTML/JS/CSS) so I don't think it could from a weird dependency ...
