Every version of kontakt, old or new, portable or regular. Just freees on opening. Not always but most often. Even if there are no libraries installed, even if it's uninstalled and the registries are cleared. Windows is not adjusted in any way and has all the redistributables. There are no viruses and i'm running samsung 990 pro ssd's. This has never happened before in all my years of using kontakt. There are no errors or crashes, happens in every daw. Happens even if i use other disks.

 

Did you have a working installation on the machine when this happened? Or did you notice this after going to reinstall it after some period of time? What Windows version? Did you try any standalone version of Kontakt yet? (not in any DAW). You might want to pick and mention one specific release you want to use, so you are not dealing with generalities.

 

You could try what is written as the last post here:
it should say sfc /scannow (not scf)

I already tried these things. But maybe windows might be corrupted. But it downloads updates regularly and everything works fine except this. It was not long ago since i installed it fresh, and even have a legal license.

 

It's Kontakt 8.1.0, i tried older too. And i also tried the standalone executable too, same results. This started happening before i reinstalled it. One day it basically started doing this. Windows 11 (26100.2605). I have a legal version. I am always trying to use the latest version of everything which is 8.1.0 at this time.

 

Ok well, when you start installing multiple copies you can end up with files and filenames conflicting. Windows updates should really have little to do with it. But Kontakt is the only thing not working, because only Kontakt uses most of those files. I would discount "Windows corruption" until you have tried everything else you can think of.

Did you use Revo Uninstaller Pro to try cleaning up everything you may not have found manually? Have you tried using the most recent Kontakt Player? That might be worth a look, just to see the results. Have you tried using it with all installed libraries moved to a backup location, so Kontakt will load with none of them?
