Couldn't get Rapture or Dimension pro activations to work in Platinum. I'm using the 64 bit versions.

Finally got them both to register properly by going directly to the exe files and then running them as administrator.

C:Program Files\Cakewalk\Vstplugins\Rapture

C:Program Files\Cakewalk\Vstplugins\Dimension Pro

Hope this isn't old news. I try to help out whenever possible, as the Forum has been very helpful to me.
