What are "all these updates"?
What is "the kb12 listed in here"? Are you referring to KB3138612?
What is the address from which you downloaded sp1?
What is the complete file name that you downloaded as sp1?
Please report the complete text of error messages rather than attempting to paraphrase them.
**********************ADDED LATER******************************
I suspect you attempted to get Service Pack 1 from the Microsoft Update Catalog and downloaded the wrong file.
To get SP1 for a 32 bit Windows 7 system:
- Go here: https://www.catalog.update.microsoft.com/Search.aspx?q=kb976932
- Click on the "Download" button for the line that says only "Windows 7 Service Pack 1 (KB976932)." This
is the smallest of the 3 options.
- Click on the link for "windows6.1-kb976932-x86_c3516bc5c9e69fee6d9ac4f981f5b95977a8a2fa.exe"
