[Image] How to get Viper4Windows working on Windows 8.1

ViPER4Windows is a reliable software that enables you to easily tweak the audio parameters for your audio card, using the audio processing object technology. The software allows you to configure suitable sound settings, for music playback, watching movies or freestyle.

As we may know, this software doesn't work properly in Windows 8.1 and up. Even we have enabled our sound card device to be used with Viper4Windows in it's configurator, the effect still remains unchanged.

Here's how to make it work:

Note:
- Tested on Windows 8.1 64-bit and Windows 10 64-bit (Realtek Audio).
- Do with your own risk!
- Backup your registry before making changes (see image).
- Sorry for my bad English.
- I am bad at explaining.
- Yeah if someone can make a better explanation, that would be great.
