Observation.
Windows 10, Live 10 I had to update to OB 2.5.1 to get the AH+FX plugin. I’ve noticed that the plugins appeared in two different Folders now (it was not like that before), one in the usual C:\Program Files\Steinberg\VstPlugins\Elektron (64bit) and the other (as a new Name) in C:\Program Files\Elektron Overbridge.
The Steinberg Folder do not contain the new AH+FX plugin so I had to work, for the first time, with the plugins in the Elektron Overbridge Folder. Those are the ones I’ve transferred to my Live Custom Folders in order to be able to use the AH+FX plugin.
In resume, the Installation process is different from the previous ones.
