Hello Tiger77,
Even if on a 64bit Windows system, most programs are still 32bit.
Make sure you use a dll file with the same bit structure as the program requesting it.
What is the exact and complete error message you get regarding this file?
When do you get this error?
Which program is requesting this file? (Look for "program".exe in error message)
What have you tried so far for solving this error?
Errors referencing "api-ms-win"* files are commonly caused by missing updates, packages, or bad updates.
Make sure you are fully up to date with Windows updates.
Install the "Update for Universal C Runtime in Windows"
https://support.microsoft.com/en-us/kb/2999226
If that is not enough, also install "Microsoft Visual C++ Redistributable Packages for Visual Studio" 2013 and 2015.
If using a 32bit (x86) Windows system, install the 32bit (x86) version.
If using a 64bit (x64) Windows system, install both the 32bit (x86), and the 64bit (x64) versions.

If install complains that this package is already installed, do "Repair" or un-install before installing.
