Every Ironstream fix is packaged with its prerequisite fixes as PTFs, which are available to download from the Knowledge Base section of the Precisely Support website.

This is not just to ensure that you have all the available service, it also ensures that you have all the latest functionality because many Ironstream enhancements are delivered as fixes.
