Bapu thank you for your quick reply.
I have deleted all waves dll from my system and hard disk. I wanted to make a new clean install , cause I did a wrong installation first time.
Now it seems that Sonar is still keeping the Uninstall Waves VST in it's system and plugin manager.
Even if I run a waves uninstalled vst , it says that this VST is not properly installed etc , etc. Of course it's not installed , but why is it keeping it there ? even after re scanning all plugins ?
I need to remove those from Cakewalk Sonar so to re install.
