I can also confirm that the pack is installed even though the CAM has a white Install button active rather than showing Installed. It's different from the other Install buttons because it has only a white outline rather than a solid blue shape.
Philwild, I was like OP and thought it wasn't installed because it didn't appear in the PiP Objects or FX rooms where most other content packs show up. Thanks for showing the correct location under Plugins!
I've found that the pack cannot be uninstalled from the CAM, but it can be uninstalled from the standard Windows uninstall screen. I uninstalled it that way but the CAM still showed that it was installed.
I then uninstalled CAM and downloaded the latest version from "Manage my subscriptions" page. After reinstalling, the Van Gogh effect's Install button is the normal blue with white letters and outline but the same behavior persists when installing it. Running CAM as an adminstrator has no effect either.
