Hi Windows 7 64 bit

For sometime now my update software has been telling me that I need to update...

Microsoft Core XML Services (MSXML)4.0

Apparently the latest version is...

Microsoft Core XML Services (MSXML) 6.0

However, when it takes me to the Microsoft website...


Where I have to download the file from, I am told...

There are multiple files available for this download.Once you click on the "Download" button, you will be prompted to select the files you need.

There are 4 different files to choose from and I am at a loss as to which one to select. (I don't want to get it wrong) The following are the 4 I have to select just one?...

Version: 6.0

File Name:





If you don't want to click the link, here are some of the details...

The Microsoft Core XML Services (MSXML) 6.0 release provides standards-conformant implementations of:

XML 1.0 (DOM & SAX2 APIs)
XML Schema (XSD) 1.0
XPath 1.0
XSLT 1.0

In addition, it offers client and server-safe components for XML over HTTP. MSXML6 is also the first version of MSXML to provide a 64-bit redistributable package.

MSXML6 has made significant improvements over previous versions of MSXML in the following areas:

Reliability - MSXML6 has addressed a significant number of stability issues particularly in resource-constrained scenarios.
Security – MSXML6 uses the principle of “off-by-default” to make loading XML data from anonymous or untrusted sources more secure. This may mean that upgrades from MSXML3 and MSXML4 will need to re-configure the MSXML6 components using SetProperty and/or SetFeature as appropriate.
W3C Conformance and System.Xml 2.0 Compatibility – MSXML6 has gone through extensive testing and a number of issues have been addressed to improve W3C conformance and System.Xml 2.0 compatibility particularly in terms of the XML Schema 1.0 Recommendation.

MSXML6 is intended as an upgrade path for existing MSXML3 and MSXML4 users except for users that leverage some of the older ProgIDs and technologies in MSXML3 and MSXML4. The following are not supported in MSXML6:

XML Data Islands
XMLHTTP10, DOMDocument10, FreeThreadedDOMDocument10
XDR Schemas

At the end of the day, I suppose what I'm really asking is have any of you updated any of these files and do I really need to?

Are you using 'Secunia'? it seems to be a 'bug' with it. ClickHere

Hi Lotvic

Yes I do use Secunia PSI. Thanx for the heads up. From what they're saying I'd be best to leave well enough alone. Cheers
