Opening Dnoise manuel and or Dnoise program

[BLevy]

I believe I finely actually successfully downloaded the Dnoise program to my hard drive as C:\...\MTU\MTUDnoise DirectXPlugin.

I have it in Windows Explorer and can open the file in the Explorer window.

Now the problem is from there nothing happens or I don't know how to activate the program so that it is a working program. Nothing happens after I open the file. It may be because I don't know what a "direct X plugin" is. Perhaps that could be explained to me also.

How do I set up the program so that it is a working program like any other software? I'm using Windows 98; I have Adobe Reader 5.0 on my drive also. Where do I go from here?
