Unable to turn off windows feature .net framework 3.5

I have recently ran the net cleanup tool trying to fix an issue (making a clean reinstall), but what I didn't expect would happen, did. I am now stuck where my windows 7 64 bit system does not have net framework 3.5 but thinks it has withing the "Turn off windows features" dialogue. I have attached a DISM log if it helps.

Things I've tried already:
- DLL Purgatory: Unable to Turn On .NET Framework 3.5.1 {PEN001}
- Installing .net framework 3.5 sp1 - received error message that I should remove it in turn off windows features.
- Running cleanups & all automated fixing methods I've found.
- SFC /Scannow - Did not help, returned error. Log attached.
- Installing .net framework 4 - It installs successfully, but does not fix any of my problems as the program im trying to run seems to need net framework 3.5 - The program is Catalyst Control Center, which I am trying to fix. The problem is that it won't, no matter what I do, display any dialogues. It is running in the system tray and all, but won't display. I did manage to get one (yes just one) .Net framework crash with it, so I started fixing it, and instead, ruined it and made my case even worse.

Now I am asking for professional help because no matter what I do I seem to ruin it.

Thanks in advance.

Catalyst info:

Tried every single guide I found on google for fixing any issues related to this. Has been tons of restarts and even more reinstalls, nothing seems to work. For anyone wanting to mention the "Remove the key named ... from %windir%\assembly I'll tell right now that it doesn't even exist there. Tried several versions of the installers. I am running crossfire (which is the start of all this hassle) which I wanted to configure, but then discovered I could not open the control center. Been struggling this for three days now, very annoying. If there is no way to fix this I'll do a reinstall, but I don't really want to do it, as I've set up this system exactly how I want it. (which took several hours of configuring and modding. And no, I haven't modded anything big, which could relate to this issue). If you mean I should reinstall my windows 7, please tell me of any programs that can be used to copy over all settings and files, but not the windows 7 system files :)

Catalyst topic again:
I've been a lot into the safemode and performed driver sweeping with driver sweeper and a few others while trying to reinstall this just to check if it wasn't .net framework that was the error.

Last option:
If anyone knows an alternative to the catalyst control center (which does the same things. Modifies the same configs etc.) I'd be more than happy

I have not seen any posts with any of the same issues like me on the internet while I've been searching, which is the reason why I post here.

Note: Cut out a little from the CBS log as I believe it was irrelevant and waay too old for this error.

Is it allowed to bump here? :)

Bumping after 4 days is allowed I suppose.

Try this Repair Install
You need Windows 7 Enterprise x64 install DVD!

Code:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /ALL /NoRestart

What happens if you run that in elevated command prompt?

I receive the error 87. Same with Disable-Feature.
Edit: Will try repair install now. Thanks for suggesting :)

Now it says that neither /all or /sources are allowed. I tried removing them and received error 0x800f080c
