Acheron: No, HFSLIP is updating iedkcs32.dll to 18.0.6001.23037. ----- Anyone: Does KB973686 even have a catalog file? setuperr.log states that msxml6.dll and msxml6r.dll are not signed properly. What's wrong with HFSLIP's handling of kb942288-v3? KB942288-v3.cat isn't being added to SVCPACK and SVCPACK.INF so setuperr.log states that msiexec.exe, msimsg.dll and msisip.dll are not signed properly.
