What could suddenly cause these 3 similar programs from loading?

Actually, I did run it over again. I clicked on the download which was in my downloads folder and ran the whole thing all over again. Don't know what's up with it.

But, I do have a bigger problem now. NONE of my programs will open. Not even IE or Firefox. I'm on a computer at the library. I restarted, even in safe mode but every time i go to open a program i get this message:

The application failed to start because it's side-by-side configuration is incorrect.

Today when I booted up I got another disk boot failure message, and had to restart the computer. Instead, i put in my Windows 7 disk and restarted it, and did what A Guy mentioned. From the install disk I went into compair my computer and opened the command prompt. Did the diskpart command, and then list volume. Then the chkdsk /r/f d: command. But, it didn't verify/repair filesystem and mark any bad sectors like it was suppose to. Instead it just gave me what looked like a list of commands and what they do like this:

ACTIVE
ADD
ASSIGN
ATTRIBUTES
ATTACH
AUTOMOUNT
BREAK
CLEAN
etc....

Not knowing what to do, I did the next command: sfc/scannow/offbootdir=C:\ /offwindir=d:\windows

Again, it did nothing but give me what looked like a list of commands and what they do. So I exited. When i restarted my computer none of the programs would work and i got that message: The application failed to start because it's side-by-side configuration is incorrect

Anything I can do to fix this issue? Sounds like my problems are getting worse. Would i be better off just to do a clean install of the OS? I didn't want to do that, but what esle can i do if none of my programs will open?

Ok, I will try that.

But, from what I read online, it sounds like this issue with with none of my programs loading has to with the microsoft C++ Visual ... Like i need to uninstall and reinstall them or something.

Btw, I tried to run the Windows Update Standalone Installer again. No wonder the dang thing runs all day long - it doesn't work. I went into the event viewer and there were numerous errors in system that says:

The Windows module installer service terminated unexpectedly. It just keeps trying to run, but it keeps terminating. It had terminated over 300 times.

In application event viewer it says:

Faulting application path: C:\windows\servicing\trustedinstaller.exe
faulting module path: C:\windows\system32\ntdll.dll


I don't know if that info helps or not.

With the two system files that wouldn't repair, the windows update issues, my computer not wanting to boot when I start it, and absolutely none of my programs working, I finally gave in and just reinstalled the OS. I didn't want to have to do that, but it seemed like things were getting worse and I couldn't even get on the internet. With your help, I might have been able to fix these issues eventually, but I didn't want to have to go back and forth to the library everyday. That and I hate being without the internet.

Everything seems to be okay now with a fresh new install. I thank you guys for all your help though.
