Step 1:
- Open and extract the zip file you downloaded above to a location on your PC.
- After extracting the Zip file, place the extracted .dll file in the directory of the program that is requesting the file. Note:
Make sure to use a 32-bit .dll file for a 32-bit program and a 64-bit .dll file for a 64-bit program. It's very important. Failure to do so will likely result in a 0xc000007b error.

If that doesn't work, place the .dll-file in your system directory, (32bit) by default, this is:
C:\windows\System32(Windows XP, Vista, 7, 8, 8.1, 10, 11)
C\Windows\System(Windows 95/98/Me), or

on a 64bit version of Windows, the default folder for 32bit .dll-fies is C:\Windows\SysWOW64\ , and for 64bit .dll-files C:\Windows\System 32\.
Always make sure to overwrite any existing files (but try to make a backup copy of the original file).
Reboot your PC, and that's all.
