Media Center 12 can be run for a 30 day trial period without purchase. The 30 day period starts from when Media Center 12 is first installed. During the trial period, Media Center 12 is full featured. Everything works as in the purchased version.
Beginning with Media Center 12, we can now, at our option, reset the trial period as appropriate steps in the beta process are complete. This means that an early version trial may be reset later on. This is all-or-nothing, the reset applies to all users.
We are sorry, but for technical and security reasons we cannot, under any circumstances, grant an extension to the trial period except as noted above. We cannot reset the trial period for individual users.
