Method 2: Replace the most frequently used DLL files inside System32 and SysWOW64 directories
If replacing xinput1_3.dll didn’t solve the problem, there is still a bunch of other files which may be causing the 0xc000007b error. Determining which one is the troublemaker may be extremely difficult, especially if more then one file is involved.
So, how about replacing them all together? Keep in mind that these are not essential OS files and replacing them WILL NOT crash your system.
The worst case scenario, after you replace these files, is that you will not be able to run some games or applications, but you will be able to boot your system as usual. If that happens, and the error is not fixed, you can easily return your original files to their locations and everything will be back to its previous state.
Complete list of DLL libraries, and their original locations in Windows 7:
C:\Windows\SysWOW64\msvcp100.dll (Microsoft Visual C++ 2010 Redistributable Package runntime library)
C:\Windows\SysWOW64\msvcr100.dll (Microsoft Visual C++ 2010 Redistributable Package runntime library)
C:\Windows\SysWOW64\msvcr100_clr0400.dll (Microsoft C Runtime library)
C:\Windows\SysWOW64\xinput1_3.dll (Microsoft DirectX runntime library)
C:\Windows\System32\mfc100.dll (Microsoft C Runtime library)
C:\Windows\System32\mfc100u.dll (Microsoft C Runtime library)
C:\Windows\System32\msvcp100.dll (Microsoft Visual C++ 2010 Redistributable Package runntime library)
C:\Windows\System32\msvcr100.dll (Microsoft Visual C++ 2010 Redistributable Package runntime library)
C:\Windows\System32\msvcr100_clr0400.dll (Microsoft C Runtime library)
C:\Windows\System32\xinput1_3.dll (Microsoft DirectX runntime library)

Replacing each of these files is pretty much the same procedure as described in Method 1 but it will have to to be done from Safe Mode. As you may assume, some files are being constantly used by Operating System, so we need to release those from their duties and that’s whey we need Safe Mode.
If you are note familiar with Windows Safe Mode, check it out here: How to Start Windows In Safe Mode. Ok, here we go:
1 Restart your system and boot into a Safe Mode (keep hitting F8 just before Windows loading screen starts)
2 Make backup copies of all files from the list above
3 Extract downloaded file and copy all files from System32 folder to C:\Windows\System32\ and all from SysWOW64 to C:\Windows\SysWOW64\
Note: In case you’ve already tried Method 1, you can skip copying Windows\SysWOW64\xinput1_3.dll file.
4 Restart your computer
