Hi,

We are trying to migrate a site we are currently building to 7.5, and we are getting issues when trying to run the VPP tool.

I have unblocked the application and i am running it as administrator. When i run it on our Windows 2012 Server i get the following error:

Could not load file or assembly 'file:///C:\EPiServer7.5VppMigrationTool\VppMigrationTool.exe' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

--- Inner exception ---

An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

When i run this on my development machine i get the following errors:

Could not load file or assembly 'EPiServer.TinyMCESpellChecker, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

Any help with this would be greatly appreciated.

Is the site functional? The migration tool will execute in an AppDomain on same location as the site so you need to have the site functional before running the migration.

ok, so an upate - on my development machine the tool seems to work.

however when i try to run it on the server (the first stack exception above) it still fails. i have admin rights on the machine, and i run it as admin. i currently have the tool located within the wwwroot folder - and the site is in c:\inetpub\wwwroot\<sitename>\

this is the last step of the upgrade for us so its pretty important we resolve it asap

I will see if I can reproduce the issue. What you could try is open the config file for the migration tool and add an element

<loadFromRemoteSources  
   enabled="true"/>

as descibed in http://msdn.microsoft.com/en-us/library/dd409252(VS.100).aspx

Ok, now I have investigated this a bit further. The problem is that even if you unblocked the .exe the other .dll files are still blocked. And because of that it fails when one of them is Loaded.

The solution is to either unblock the zip before extracting it or add the element <loadFromRemoteSources> as described above.
