According to all 4 crash dumps its the file “Msvcp140.dll” thats making the crash. First Msvcp140.dll crashes , then Kontakt crashes and last Cubase is crashing.
Start by downloading the Visual C++ package from “techpowerup” It will install both the 32 and 64 bit versions. Read the install notice on the webpage and to make it easy i´ll post the link aswell.
