How do you open a .msu file?

How does one open an ".msu" file? I'm trying to install PowerShell 2.0 on Windows XP SP3. I read that you can use something called wusa.exe or a packet manager program?

@Keith Thompson That link explains nothing... – Wormhole Xd – 2013-08-06T01:19:39.990

From the linked page: "You can also double-click the .msu file to install the update package." Did you try that? – Keith Thompson – 2013-08-06T02:22:43.913

Please include the things you tried and how they failed. @KeithThompson's link is exactly what you are asking for. If the information there does not help, mention that you have read it and explain what happens when you try to follow MS's instructions.

You can't use MSU files on Windows XP. This is the new Update format for Vista+.

You must use the WindowsXP-KB968930-x86-ENG.exe from here:

Update for Windows XP (KB968930)

http://www.microsoft.com/en-us/download/details.aspx?id=16818

This package includes the following components: Windows PowerShell 2.0 and Windows Remote Management (WinRM) 2.0. After you install this item, you may have to restart your computer.

This should be marked as solution. – Greg0ry – 2014-12-03T12:57:36.223

Try the following command to open the MSU file:

expand -f:* "file.msu" %temp%\ExtractFolder

wusa.exe is the program that will install these. Typically you can double click on the .msu and wusa.exe will take over from there, otherwise try something like c:\windows\system32\wusa.exe {path-to-msu-file} from a command prompt. – LawrenceC – 2013-08-06T03:17:08.660

Of course. My answer was more related to the first part of the original question "how to open," rather than "how to install." – Jack – 2013-08-06T12:17:52.470
