When one of our Managers opened up the PowerPoint slide deck that Power View generated, he got the following error:
Some controls on this presentation can't be activated. They might not be registered on this computer.
I had found some references to the RC0 timeline indicating that if you had PowerPoint x64 you would get this issue because the Silverlight 5 x64 bits had not been release yet, so there was a platform mismatch. However, in this person’s case, he was running the 32bit version of PowerPoint.
When he checked the version of Silverlight, he discovered that he was running version 4.1.
I pointed him to the
Silverlight 5 download
to install the latest bits. After that was done everything was working as expected.
