VST3 UID?

[musictop]

Where/How can i set vst3 UID?
On Reaper an Abelton only one of two of my instruments scans and works - after one is removed the other one scans and works normally. In Reaper they only work if you set the app to allow vst3 plugins with same UID.

@musictop This is probably the plugin code in project preferences
