Assembly must be registered in isolation error

Question

I'm trying to load a custom workflow activity onto a crm server. I loaded the project onto the server and have been using the CRM Plug-in Registration Tool. The server is CRM2011 and thus supports .NET 4.0 activities. However, when I press the "Register" button (After the assembly has successfully loaded onto the Tool) the following error occurs:

`Unhandled Exception: System.ServiceModel.FaultException'1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: Action failed for assembly 'ExecuteSQLJob, Version=1.0.0.0, Culture=neutral, PublicKeyToken=914788311ab3af7d': **Assembly must be registered in isolation**.

What does registering in isolation mean? Is it simply a matter of where the assembly is saved on the server or is it more complicated?

I've been following MSDN's tutorial's so far but can't find an explanation for this.

Thanks!

If you aren't a Deployment Administrator then you will need to register it in isolation mode.
