Where can I find netfx.msi when patch .NET Framework 1.1


When I patch MS/KB953297 on .NET Framework 1.1, after answer quite a few questions, the system give me the following message.  When I click Browse…, actually it is asking for the file netfx.msi.  I don’t think it is in another admin’s temp folder, where can I find this file?

The first article I found that could fix the issue is an official MS/KB839547, it explains pretty well and understandable in the CAUSE section, but the WORKAROUND need to reboot and reinstall .NET Framework 1.1, and then probably I can implement the patch.  Is there too many reboots and too much work?

I searched again, and found another article, in a not-quite-official MSDN blog.  This one provided a little more information and a neat solution.  Does that patch ask for netfx.msi?  What if we just download the file and tell the system where to find it.

Here are the steps:

1, Download the .NET Framework Version 1.1 Redistributable Package from here:, this link is provided in KB839547.

2, Extract the package using command line, dotnetfx.exe /t:c:\temp /c.  You will see the file netfx.msi in c:\temp folder.

3, Run the patch KB953297, and when prompted for the file, click Browse… and locate the source in c:\temp or wherever you put in previous step, click OK again.

Voila!  KB953297 is successfully installed.

Thanks to Aaron Stebner for his article.

    I guess i’m not very smart. I have the same problem, but when I try to extract using the command here I get a reply “System cannot find path specified.” I’ve tried moving dotnetfx.exe to different folders and adjusted the command, but to no avail.

      You have to do it from the directory where the dotnetfx.exe file resides. Just cd to wherever you downloaded it to and run it from there.

    When I get prompted to find the file, I select it and get the message that it is not a valid file for the product Microsoft .NET Framework 1.1 … How is this possible if it works for everyone else?
