KB2840628v2 hates me..
last months KB2840628 hated me too and wouldnt let me install until I ran repairs on the system. and now again the same problem with v2?
kept getting 0x80070643 and 0x643
so far manually download the update and it starting installing and then rolled back saying there was an error. which was 0x80070643
edit: I ran net framework 4 repair and then ran the update and it installed.
