As a convenience, RTDA has released 2011.09r2, which is a release that includes the 2011.09 baseline release as well as any updates that have been published since the original release date. New installations of 2011.09 should use this release. Existing installations of 2011.09 will be equivalent if all updates found in the 2011.09 directory of the downloads area have been installed.
As a reminder, make sure that updates are applied to the exact version for which they are downloaded. Do not, for example, install a 2011.09 update to a 2011.09r2 release. Also, because this special rollup release is simply 2011.09 with all of its updates included, any license file that works with 2011.09 will also work with 2011.09r2.
