"Installation" failure


I get the following after copying the files from the VS2010 folder to the addins folder, then going to Add-ins manager and check the add in and then when I hit ok I'm greeted with the following message:
Win7 x64, VS 2010Premium, sv-FI, UAC on


Microsoft Visual Studio

The Add-in 'Xaml Localizer' failed to load or caused an exception.
Would you like to remove this Add-in?
If you choose yes, the file it was loaded from, 'C:\Users\sdahlbacka\Documents\Visual Studio 2010\Addins\XamlLocalizerAddin.AddIn', will be renamed.
Error Message: <Unknown Error>

Error number: 80131515

Yes No

Googling by error number "80131515" gives idea that perhaps addin assemblies were blocked by system, because they originated from internet.
As a workaround you can in Windows Explorer click Properties of each addin .dll and click "Unblock".

I unblocked the files one by one and that worked, in retrospective it would have been easier to unblock the zip file before unpacking though...
