In AX 4 the application and kernel version details in help/about do not appear to show you which service pack is installed, this can make it difficult to tell which updates a particular system is running. Although the service pack isn’t shown it is possible to tell which service pack and updates are installed by understanding the version numbers:

AX 4 SP1                               4.0.2163.0

AX 4 SP1 with DIS layer        4.0.2500.XXX

AX 4 SP2                               4.0.2501.116

AX 4 SP2 with DIS layer        4.0.2503.XXX
