[7SP1HomePre x64] Can't install programs

[HauntedCookies]

I wasn't sure where to get help for this but i suppose anywhere is better than me spending more hours figuring this out on my own,
my computer was a custom built and has been back to the person who made it a bunch of times for repairs and he never fixes it so i've been attempting to figure out the errors myself
I have attached my CheckSUR.log i believe the issue is a missing manifest file but i could be wrong. When i install a new program any new program i get an error "0xc000007b"

which lead me to looking at the "turn windows features on and off" which was blank and then i started the system update readiness tool to see if that could fix it but sadly it's still blank and i still can't install anything, some updates work but if they install on their own it makes my computer much slower so have to system restore and install them manually.

i'm very new here so forgive me if the file isn't attached i'll put the information here as well
