impossible to open battery 4 on Komplete Kontrol and S49

philmusic39

Good morning
After uninstalling and reinstalling the trial version of Battery 4, it appears in Konplete Kontrole, but says "cannot find the plug-in.
I scanned several times and battery4 still does not open even though I see and hear the sounds of the library.
Can you help me understand.
Sincerely
