The error message is quite clear:
The DLL file could not be found in one of the directories that are searched (see Dynamic-Link Library Search Order (Windows)[^]).

So copy the file to one of these directories or specify the full name with path.

[EDIT]
The error may be also thrown when dependencies can not be found (the DLL requires loading other DLLs). You may use the Dependency Walker (depends.exe) Home Page[^] to check this.

tried but not working

The DLL itself may have dependencies (requires to load other DLLs). If such a DLL can't be found, the error will be also thrown.

You might use the Dependency Walker (http://www.dependencywalker.com/) to check the dependencies. I will update my solution.

Tried Dependencywalker but Not working

What did you tried?

Load your application or the DLL with the Dependency Walker and check if all dependencies can be resolved.

Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.

Dependency Walker Error

Jochen Arndt 19-Apr-16 9:23am

That warning may be ignored in some cases. Check if there are missing modules (not found errors).

If you are really sure that the DLL itself can be loaded, you have to ask the author of the DLL for help.
