Do SYSmark® 2012 installations expire after a certain period?

Yes. Some applications packaged with the benchmark suite, such as Microsoft® Office® 2010, will expire 30 days after installation. Once the applications have expired, the HDD containing the SYSmark® 2012 installation must be reimaged with a new copy of the operating system, and a new instance of SYSmark® 2012 must be installed.
