Trying (and failing) to create my first Win7PE SE

Here are the steps I took:
1) Download and install Windows AIK
2) Download and unzip Win7PE_SE_Small_2015-02-20
3) Move unzipped subdirectory under Program Files
4) Click on Download tab
5) Click on Win7PE_SE under "recommended" then click on "Download".  Lots of stuff is downloaded
6) Insert Win7 Ultimate Install disk (that I used for my Windows 7 installation) in DVD tray. Copy all files to C:\Win7
7) Click on the Step 1&3 picture under the "Script Tab" and get "WIndows Phtoo Viewer can't open this picture because either the picture is deleted, or it's in a location that isn't available.
8) Click on "Source" Tab and click on Source directory and point it to c:\win7
9) Click on "Play"

Get failure notice: "Build stopped due to an error"
CLick on "OK" button

Thre is an Errors (1): RegHivLoad -Faile to load registry hive: [WB-SOFT] From file: [WIndows\system32\config\software]: unknown error:


Now what?  (I tried to upload the log.7z file yesterday, but my post seems to have disappeared.)

It appears that the EzPE3 version *does* work, so I will base my winPE on it.  Still wish I knew what I am doing wrong with the Win7_PE_SE_Small_2015-02-20, though.  Probably something simple.

1) Download and install Windows AIK

No need to

Now what?  (I tried to upload the log.7z file yesterday, but my post seems to have disappeared.)

after 10 posts you can 
(workaround: give link inside codebox)

3) Move unzipped subdirectory under Program Files

!!! Why

This may be the problem if your host is x64, (windows x64 specialize ( limits )  C:\Program Files\ folder for only x64 applications ...)
