Except where indicated, these are incompatible with App-V 4 and 5 packages right now. When you sequence a package and see a MSXML Runtime file, grab the version string and consult these tables to find the exact installer that you need to use external to the package.

 Microsoft has a KB Article listing MSXML versions that contains many more versions than those shown on this page (but without the details). Generally speaking, the different major versions of MSXML may coexist as side-by-side components on the same system. Within a major version, we see that components are replaced. Security Updates seem to ignore the resource file, while Service Pack releases update both files.

MSXML Version 1 and 2!

 These versions are obsolete. (I hope).

MSXML Version 3!

The Installers for MSXML 3 are no longer available via Microsoft. There are some patch installers available, but this is so old, and Windows 7 includes the newest of the MSXML 3 as part of the OS, so I didn't bother documenting them. You probably won't run into one of these.

• C:\Windows\winsxs subfolders; look for folders with names like C:\Windows\winsxs\amd64_microsoft-windows-msxml30_[guid]_[VERSION]_[lang]_[guid] or C:\Windows\winsxs\x86_microsoft-windows-msxml30_[guid]_[VERSION]_[lang]_[guid]
• C:\Windows\System32 folder; look for files with names like msxml3.dll> and msxml3r.dll
• C:\Windows\System32/[Lang] folder; look for files with names like msxml3.dll.mui> and msxml3r.dll.mui
• C:\Windows\SysWOW64 folder; look for files with names like msxml3.dll> and msxml3r.dll
• C:\Windows\SysWOW64/[Lang] folder; look for files with names like msxml3.dll.mui> and msxml3r.dll.mui

The version numbers for the files in MSXML 3 use a format of "8.*0.*.*", where the first asterisk indicates the Service Pack level. When the third level is 7600, the file came with the Windows 7 RTM release, 7601 means it came with the 7 SP1 release.

MSXML Version 4!

Because Windows 7 ships without any MSXML 4 version, this is what we tend to catch a lot of. Unlike the VC runtimes, it is possible to just include the latest version 4 on the sequencer and clients and be done already.

MSXML 4 Files show up in the following locations:

• C:\Windows\winsxs subfolders; look for folders with names like C:\Windows\winsxs\amd64_microsoft-windows-msxml2_[guid]_[VERSION]_[lang]_[guid] or C:\Windows\winsxs\x86_microsoft-windows-msxml2_[guid]_[VERSION]_[lang]_[guid]
• C:\Windows\System32 folder; look for files with names like msxml4.dll> and msxml4r.dll
• C:\Windows\System32/[Lang] folder; look for files with names like msxml4.dll.mui> and msxml4r.dll.mui
• C:\Windows\SysWOW64 folder; look for files with names like msxml4.dll> and msxml4r.dll
• C:\Windows\SysWOW64/[Lang] folder; look for files with names like msxml4.dll.mui> and msxml4r.dll.mui

MSXML Version 5!

The Installers for MSXML 5 is associated with Microsoft Office 2003 and 2007. I didn't bother documenting them. 

MSXML Version 6!

MSXML 6 Files show up in the following locations:

• C:\Windows\winsxs subfolders; look for folders with names like C:\Windows\winsxs\amd64_microsoft-windows-msxml60[.resources]_[guid]_[VERSION]_[lang]_[guid] or C:\Windows\winsxs\x86_microsoft-windows-msxml60[.resources]_[guid]_[VERSION]_[lang]_[guid]
• C:\Windows\System32 folder; look for files with names like msxml6.dll> and msxml6r.dll
• C:\Windows\System32/[Lang] folder; look for files with names like msxml6.dll.mui> and msxml6r.dll.mui
• C:\Windows\SysWOW64 folder; look for files with names like msxml6.dll> and msxml6r.dll
• C:\Windows\SysWOW64/[Lang] folder; look for files with names like msxml6.dll.mui> and msxml6r.dll.mui
