IIS 7.5 Application Initialization 1 failed to install

Question

I'm using Web Platform Installer to install "Application Initialization 1" but I get a general "Fatal error during installation" message.

In the log file I see:

MSI (s) (9C:24) [14:04:47:315]: Executing op: ActionStart(Name=ExecuteInstallWindowsHotfix,,)

It looks like it's trying to install a hotfix.
I've having this problem on 4 different machines with Windows 7 Enterprize x64

Any idea how to fix this?

Update

I got the actual msu file from my "Temp" folder and I can see the hotfix it's trying to install.
it's a file called Windows6.1-KB2684600-v2-x64.msu
Support Link= http://support.microsoft.com?kbid=2684600

When I try to install this hotfix manually I get "The update is not applicable to your computer "

Update 2
I also asked on iis.net but they weren't able to help much

Have you fix this problem? I have same problem here. Somehow after re-installing windows and made some windows updates, the application initialization installed successfully. In another day after have a complete update, it ended prematurely. I have spent many days just to try to figure out what is the problem by re-installing windows over and over again, to find out why the "hotfix" says "not applicable for your computer". Maybe not compatible with another windows update? — Buzz
@BennyChen Unfortunately no. I ended up using other machines to do my job...I also asked on forums.iis.net but they didn't help much forums.iis.net/t/1233184.aspx — George Vovos
@BennyChen Added a bounty.If it draws attention someone might be able to help you — George Vovos
When your trying to install it manually, are you sure that its a 64 bit version msu. — nik_boyz
@nik_boyz Yes,it is the 64 bit version.(I tried the 32 one also and I get the expected message that it is not the correct version) — George Vovos

I got the same problem with my new laptop at work. I contacted Microsoft Support and after trying some different things they finally found out what was causing the installation of Application Initialization 1.0 module to fail on Windows 7 Enterprise SP1 x64 machine.

We found that hotfix 2684600 which needs to be installed for Application Initialization module, is supposed to update the iiscore.dll to version 7.5.7601.21943. However, our existing machine’s iiscore.dll is already at version 6.5.7601.23403, it would make sense that the hotfix is throwing the “not applicable for your computer” error during installation.

Digging further, we found that the version 23403 gets updated when KB 3125574 is installed through Windows Update.

We followed these steps to resolve the issue:

remove the KB 3125574
install Application Initialization module
then install the KB on top of it
