I installed PSP Audio Triple Meter VST3 this morning into c:\program files\common\vst3. - i.e default. Nuendo 12 seems not to be scanning and picking up on the plugin - but it has def installed in the directory. I installed some Blue Cat meters also this morning with no problem. Also authorised the PSP meter in reg edit.
Anyone have any ideas. Is there any cache that can be cleared that might affect whether the plug in gets scanned or not. Will check it with Dorico 5 as well.
