Can't install NET Framework 4 Client Profile, error code: (0x80070643)
I've been struggling for the last several days, trying to fix several problems with my PC. It started with some keyboard keys which didn't work correctly. I eventually fixed that problem, but the new one appeared. I couldn't download 170+ window updates, after having run Repair Install.
Some of those updates have been installed successfully, other failed to install.
After many attempted fixes and solutions, I decided not to install all 170 updates at once, but to check the "update packages" in chronological order. First the oldest ones from 2011, then 2012 and so on. First three years went smoothly, 2014 was a bit of problem. Then ensued next round of fixes, hotfixes and various solutions which I found online.
The usual scenario was: out of x updates x-1 installed successfully, one failed.
Then > all these fixes
I went through that cycle several times.
I scanned my system a couple of times in between, (Super AntiSpyware, ESET online scanner).
To repair potentially damaged system reg keys I run Reenable II Lite as well.
Some failed updates I downloaded directly from Microsoft Update Catalog and installed them manually.
To cut an (already long) post short: I eventually, after 4 days of failed attempts - succeeded in installing all 170+ updates, but...this last update I am not able to install. Attached is the installation log.
(I forgot to say that I am not able to reach Windows Defender. When I click on it I always got pop up notification saying that the WD is turned off. Then I clicked on the words "click here to turn it on". Since nothing happened, I decided to let it be turned off, and I installed Malwarebyte 3.0, Trial version, instead)
In short: lot of issues here. Mouse wheel also does not work. Can't zoom in in Photoshop. Can't increase/decrease fonts on the webpage, etc...
I'd be extremely grateful if anyone could help me bring my PC in order as it was a week ago when everything worked as charm.
