KB2840628v2 hates me..

[dskiller]

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.

For others that find this thread, there are a number of problematic updates to .NET 4.

The simplest solution may be to install .net 4.5 (and its patches).
Download Microsoft .NET Framework 4.5 from Official Microsoft Download Center
