Hi everyone,
I’m having an issue with Kontakt 7.8.1 Portable on Windows 10 IoT LTSC (21H2). The libraries are detected and load successfully, but when I open any instrument, the custom graphical interface (GUI) doesn’t appear. Instead, I only see Kontakt’s default keyboard view.

I’m using libraries like GetGood Drums (P4 Kit/PV), but the same issue happens with other libraries that normally have a custom interface. I’ve confirmed that the library files are complete (including .nkr, .nicnt, and .nki).

Here’s what I’ve tried so far:

• Running Kontakt as administrator.
• Reinstalling all MS Visual C++ Redis packages and the .NET Framework.
• Removing and re-adding the library.

I’m wondering if this could be caused by my Windows version or a compatibility quirk I am unaware of with Kontakt 7.8.1.

Has anyone experienced a similar problem or knows how to fix it? Thanks in advance!

 

I suspect it could be something with OpenGL. There was a tool distributed with Kontakt Portable, which allowed to solve such problems. (I had a black Kontakt Portable, too, in Win10 LTSC.)

 

Hey thanks for the quick answer, I tried that tool in all its options, but I don't seem to get any different result . The interface itself woks, it's just the library that shows loading progress but with no GUI

 

I'd try renaming Settings.cfg in the portable folder (requires re-registering libraries) to start with default layout.

 

Done, still no luck

 

There is a tool named 'Win7 come back.exe' in Addons folder of the downloaded portable folder. Run it as per the instructions. This should fix the compatibility problem if any. I am currently running Kontakt 7 and Kontakt 8 both on my Windows 8.1. It lags a bit when opening and closing but everything else works fine.
