ERROR in RUNNINg third party programs with .EXE file extension.

Hello,

I have downloaded third party software having .EXE extension on my WINDOWS 7 Pro system( 32 Bit OS) This Program is Virus-Free and Clean . I tried to RUN the program. But I could even open the file , could not RUN and INSTALL it on my PC Desktop

I tried System File Checker tool ( SFC ) to RESTORE the files , if missing or corrupted , if any , by typing Command Prompt in START search and Running as Administrator by right clicking Command Prompt and BY GIVING COMMAND >
c:\users\Administrator>sfc /scannow.

However, this also gives error message as : "sfc" is NOT recognised as internal or external command , operable program or batch file

Can anyone tell me Urgently the solution over this which will allow me to RUN the program with .EXE file extension which I have downloaded to my system

Thanks, Shashikant

Hello Layback Bear ,
I already tried Brink's STEP 2 >sfc scannow command prompt as stated in Tutorial there . But instead of c:\windows\system32> it gives c:\users\Administrator
and when I try it, it gives ERROR as " SFC is not recognised as an external or internal command , operable program or batch file . In such situation , what shall I do ?

My Third party programs are :: 1) Bitcoin Generator.exe
2) iLivid ( Video Downloader )
3) Malawarebytes (Anti-Malware program ) This file has been extracted successfully and shows .exe file too. But the ERROR message states: “Windows can find .exe file “
4) Updater V4.rar ..This RAR file too, can not be opened and RUN

Hello,

I would appreciate , if you reply back soon on this issue , which I already tried as suggested by you

I wait your reply

Thanks,

Hello,

Thanks for info . I scanned the system by download of ELEVATED Command Prompt.
It reported some corrupted files, but was unable to fix some of the them ,I checked up the LOG Report :: as given in c:\windows\logs\CBS\CBS.log

Most the files and registry keys are repaired ..But , Please guide me further how to FIX only some of the corrupted files which could not be fixed by SFC command .

Thanks for your time
