That Update was done for use in INF R1 mainly, not for S:AH, I test it and works, so it seems to work ok, but it's more like a little advise...
Try to download the Latest Version of 7-Zip at
www.7-Zip.org, I believe I compress it using v4.28, the Compression algorithm is usually incompatible for older versions of the program, try using the last 7-Zip version
I'll have to upload a Full RAR File..........

EDIT:No, you don't need to extract files 0002 to 0005, once you have all the 7z Files, you just select "Extract" over the 1st, and automatically all the others are uncompressed.
Once you uncompress it with 7-Zip, check in the "Properties" and see the size of the folder, it should between 90 and 100 MB.
