Its Rafal Sosnowski from Microsoft Dubai Security PFE Team. Some time ago I put together all versions of MBAM (Microsoft Bitlocker Administration and Monitoring) tool into one table. Small disclaimer: It is based on what I have seen in the wild and is not official information from Product Group.

As you can see in above table, some of the version numbers will apply only to client side binaries, some of them only to server side binaries. So it is fine to have client and server components on different version levels (within one major release: 1.0; 2.0; 2.5).
Also older clients (like MBAM 1.0) can still talk to the latest MBAM server (like MBAM 2.5 SP1) however we always suggest to upgrade both client and server side and keep them on most recent version.
If you want to check what is the current version of MBAM server side components navigate to the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft BitLocker Administration And Monitoring\Setup
If you want to check what is the current version of MBAM agent navigate to the registry:
Or go directly to the filesystem and check properties of the agent service’s file which resides by default in:
C:\Program Files\Microsoft\MDOP MBAM
I hope this quick post was informative and if you have any MBAM version not listed here, please let me know and I will add it to the table.
