Hello Doctor V,
Uninstalling is quiet straight forward, and like most other applications on Windows (I assume, as you haven't said otherwise)
The install folder will be at either >> C:\Program Files\NCH Software or >> C:\Program Files\NCH Swift Sound depending on the application.
When you locate the applications folder, you'll be presented with an uninstall icon.
PS: We most certainly do answer questions from non paying customers, as well as pre-sales inquiries, it just takes a little longer.
PM if your issue persists and you aren't getting feedback from your support ticket.
