Contol Builder M version 3.2 Build 11 (3.2/11) software.

DO NOT USE THIS VERSION
The reason that these versions are unavailable is that they have some extremely serious bugs that will crash your controller. Having been one of the poor "beta testers" who suffered through every version between 3.2/7 and 3.2/16 during commisioning of a live project I can assure you that you absolutely do not want the pain associated with these versions.
All of the sub versions of CB 3.2 are source code compatible. There is no need to use 3.2/11 and you should use the latest version available. If your controller firmware is using one of the affected releases then it should have been upgraded long ago and IMHO should be considered as unstable and not fit for use in a live plant. Downloading applications to the controller are very likely to crash the plant.
