Be aware of the 2913703 it is post-SP1 and not R2
today i saw that MS had published the update 2913703 with subject Applications that use dynamic variable lists are not installed in System Center 2012 R2 Configuration Manager.
If you look closely, you’ll note that this KB is for the R2 version of CM 2012.
you also can notice this on the “Applies to” section: Microsoft System Center 2012 R2 Configuration Manager
however, if you read the KB, you’ll notice that the version of the Basesvr.dll is 5.0.7804.1405 while on a CM 2012 R2 it should be 5.0.7958.1000…
anyway, if you request the hotfix, you’ll also notice that the file name is ConfigMgr_2012_SP1_CU3_KB2913703_ENU…
I did speak with Microsoft and they did a mistake, this KB is post-SP1 and not R2. they are currently preparing the updated version of the page
