Live Office App-V virtualization

Hello,

One of my customers is trying to run Live Office (BI 4.1) on an App-V environment. He virtualized Live Office plugin and tries to run it on a client. The Live Office plugin seems to work fine and users are able to login to the BO-server with it and select a report. But after that (selecting an element of the report to use in excel) Live Office throws an error: "the invoked member is not supported in a dynamic assembly". This error seems to be related with .Net framework, but according to my customer .NET Framework 4.5.1 is installed and available for the applications. On the server where Live Office was installed initially and virtualized it works fine, so this issue has something to do with virtualization I think.

Does anyone have experience with App-V virtualization and Live Office? Is this scenario supported/tested by Business Objects?
