Problems with Kontakt 8 in Reaper

Since one mounth, in Reaper, each time I want to open in FX Kontakt 8, Kontakt 7 or Massive X, there is the error message "Effect configuration is preserved". I did lots of stuff to correct this (check installation paths, reinstall both Kontakt 8 and Reaper, check that vst3 file is well located, testing if Kontakt 8 and Reaper worked well alone, etc…), but there is allways this problem. I need to work and it's more and more anoying for me. Could someone help me ? Thx !

Would need to see a screencap of the error message - but off the top - this sounds like a Reaper message.

I agree with VocalPoint that this immediately sounds as a Reaper error more than a Kontakt error and I would expect that you'd maybe have better luck asking in the Reaper forum.

check that vst3 file is well located

I am curious to what this means , what is "that vst3 file is well located" ? Do you have the VST3 installed to the default location ? (C:\Program Files\Common Files\VST3 ?)

Did you try the generally suggested Clear Reaper Cache and Re-Scan Plugins ? (Go to Options > Preferences , Select Plug-ins > VST from the left-hand menu, Click the Clear cache/re-scan button)

each time I want to open in FX

I see that your post is tagged with Komplete Kontrol software, are you opening the above mentioned in Komplete Kontrol software inside Reaper ?

Here is the screen of the problem, there is the same if I tried to load Kontakt 7, Massive X and even Komplete Kontrol.

Out of Reaper, everything seems good.

And for answer PoorFellow, yes, VST3 are in default locations, and the paths are mentioned in Reaper (and for proof he found the VST, just could not load them), and yes I already cleared cache/re-scan lots of times.

But reinstalling Reaper and downloading updates never changes this…

Not a Reaper user - but this sure looks like you are trying to insert an VST "effect" where Kontakt is an actual VST "instrument". They are vastly different - even in Reaper.

Has this ever worked for you?

I concur with VocalPoint , what you are trying to load is not effects plugins.

Did you try starting with a fresh layout and then select the "Insert virtual instrument on a new track" ? And then select VST3i Kontakt 8 ?

I have no problem doing that.

P.S.

I can however not load Komplete Kontrol (3.x.x) in the same manner (for me it crashes Reaper)

The first strange thing is that I ever worked in putting VST from "FX", and it always worked until the end of July 2025…

Second thing, I tried with your solution but the problem is still here… exactly same error message…

I am a complete novice with respect to Reaper so I don't know why that is , but if it worked for you then it worked for you.

I think that you should try asking in the Reaper forum or Reaper support.

Of course then you can also try asking N.I. Support (all) if you think it better.

In case that you need guidance contacting support : How to contact NI Support and How to get in touch with our Customer Care

I managed to get Kontakt 8.7.1 to load in Reaper by setting it to run as dedicated process.
the issue now is that only 3rd party libraries will load (such as the blueprint libraries from Fracture Sounds and the Heavyocity libraries).
Analog Dreams, Shreddage 3, Hypha, Irish Harp…. all of them crash to desktop.
