I have no idea what you mean by "dormant points".
WCG test the BOINC clients themselves and recommend only those releases that pass to THEIR satisfavtion. 6.4.5
DOES NOT. Also, the one from WCG is 32bit, NOT 64bit, and puts a WCG logo in your system tray instead of the generic BOINC one.
If you want to be sure, click the "display all versions" (or whatever it's called) link on the BOINC page and pick the 64bit version of 6.2.28
