Getting an error code 80073712 while trying to install KB2799494

Hi there,

New to the forum and not an expert of computer at all.
One of the latest windows upgrade KB2799494 has failed to be installed. Error code 80073712. I'm using windows 7 Ultimate x32.
Several things I've already tried (by Googling):
System Update Readiness Tool, according to the logfile CheckSUR.log there're no errors.
ran the fix it tool (several different versions)from Microsoft, didn't do anything.
SFC check showed everything's fine. (but it finished really fast, like about 10 sec)
download the update and tried to install it manually, but no luck.
clean boot, windows troubleshooter, also no luck.

Other updates have been installed successfully but only this one, and this never happened before. Hope someone could maybe help.

thanks for the quick reply.

thanks for the information.
About the restore, pity I don't have any restore point before the first attempt of trying to install the upgrade.
Any other thing I could try?

man you must be some sort of prophet :-P just joking, you must have already met a lot of similiar situations.
Checked the upgrades listing, it's not there. should I post the CBS logfile? if yes, should I run something first like SFC check, because things are pretty a mess in my computer right now, have tried a lot of things.....

just saw your post after I clicked the post button....I'll do what you asked

CBS.log as requested.
