I Get an error every time I try to update Windows 8.1 or update Defender (EXE On top "Class not Registered")

I think my lap top has a lot more problems, then the sun has Hot spots! :)
(not that I am down playing any one's situation, nor want to sound cynical or Condescending).
Though many of my issues have been resolved through a LOT of time, tech support and a couple friends and personal researching.
But I get the "Class not Registered" Every time I try to update Windows,
(I have Mozilla Firefox 30 and Windows 8.1)
On Top of small Error box, I get EXE..on top. But Inside the error box "Class not Registered"
Some of the other issues or problems were self inflicted by not researching properly, so to say the least I am being extremely cautious.
I have the same issue with Class not Registered, and looking for some ideas or hopefully the solution.
After I try running a windows update and any updates for my virus scan "Defender" which is what I believe windows 8 and 8.1 uses, I am not sure about Vista or Windows 7 have, I never used them.
I went right to 8 through a new lap top. Then I got Windows 8.1 (that was about a month ago)
But if anyone does find or even know an answer please reply as soon as you are able, anyone else who may just be reading, if someone gets anything that did work for them, Please Let me know.
Due to time I couldn't read through more Forum suggestions or links that may work for
My Error EXE. "Class Not Registered" :)
BUT will return later in day. Maybe anything I found an answer for I can pass on. i Have had plenty issues since I had a type of crash (Or whatever it was when I was online with a Tech from Microsoft and and he had it so both of us could control the Arrow cursor, I double checked phone number for MS and it checked out legit,
That was the beginning of many days of constant repairing That was back around July 6th 2014 Thanks to everyone who even just reads this, BuddyD

This is might because of your prior change in softwares. so first you have to do run '''sfc''' in run command. and then you see the specific problem which causes this . Since System File Checker (sfc) scan will make Windows replace corrupt or missing system files on your computer.

Why do I get this error every time I try to update Photoshop CC

The error I get after getting to 99% completed every time is as follows:
Adobe CSXS Infrastructure 4
Installation failed. Error Code: U44M1P7
I do not understand why this problem that seems to be somewhat universal cannot be corrected. Please help! I simply cannot upgrade through the Creative Cloud upgrade service and it will not even process it through the application. All of my antivirus and firwalls are turned off.

I am not a computer whiz, so having to go into things I do not understand is not something I want to do. It still doesn't tell me why the update fails. I have been through this before and the only thing I was told is that I needed to uninstall the application first. Is that what must happen for each update? If so, that needs to be fixed. And what happens to my actions and all things installed in CC, like brushes and presets? If I download a new version of LR, is that going to be the same?

I am really angry that I get this message every time I try to update Itunes.
“The File ‘C:/documents and settings\DEAN\Local Settings\Application Data\Apple\Apple Software Update\itunes.msi’ is not a valid installation package for the product itunes. Try to find the installation package ‘itunes.msi’ in a folder from which you can install itunes.
What kind of gobbledegook is that? Are you or Microsoft crazy. Us computer users need simpler instructions. Or you need to write your programs so that they work.

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

HT201210 Error every time I try to update my iphone 4s to iOS 7

it gives me an error message saying "software update unavailable- software update is not available at this time. Try again later" What do I do?

Youre not doing anything wrong, its just the servers are probably flooded with people updating. It happens with almost every OS update so dont let it get to you. Just be patient and eventually it will work.

I get an error every time i try to download a podcast

The error says that I need to get authorization from the podcast website ( it says this for each one). I have tried to go to the link that it suggests but nothing comes up. How do I fix this error?

Disable your firewall.

I get an error every time I try to run the Air installer to install Acrobat Pro XI on my Mac

Here is the error message:
This application cannot be installed because this installer has been mis-configured. Please contact the application author for assistance.

Not when that is the answer and poster do not bother to read it
You DO NOT have an iPhoto issue - you have a third party software issue - and the answer is to contact the software provider - Not really a difficult concept for most people - contact the author for help with their product

I get 403 errors EVERY time I try to download something.

I was just looking for mods for Oblivion on tesnexus when I suddenly couldn't download anything anymore. I had been downloading things all day, but nothing that would change anything this drastically. I went to other sites and found out I couldn't download anything there either. I've tried clearing my cache, history and cookies to no avail. I tried disabling my plugins and antivirus and again, nothing. I tried resetting my computer, but it was another failure. I tried using IE and still I couldn't download the files. I've been working hard to mod Oblivion, but all that effort seems to be for nothing since the only option I see left is to format my hard drive and start over... I desperately need help so it doesn't come to that. Please HELP!

I can still access the web, but I can't download anything.

Run the cleaner, reinstall.
Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
And don't bother with running any updates unless you really need them or they fix a critical issue relevant to your workflow.
