My Komplete Kontrol 3.5.3 version from R2R is falling back into demo mode literally after every second or third launch. I had Bobdules version installed previously, but deleted everything using Revo uninstall and also deleted variouzs registrations remainders manually.

Can anybody help?


Thanks

 

You said "deleted with Revo", but did you do a Monitored Install of the previous version you had installed? If not, you can have different results.

 

Thanks for coming back to me. Not exactly sure what ou mean. I never installed the R2R version before, only relight on Bobdules version. But I do have other R2R and Bobdule Native products installed.

 

Check your R2R KompleteKontrol nfo. Are there any pre-requisites to be installed like NetBlockRuntime (which also requires R2R certificate) ?

 

While you install a program using Revo Uninstaller Pro monitored install, it monitors your system and records all the changes, so it can fully remove the program later. Otherwise, it is just working like a cleaner and removing everything it can find where it is expected.
Your first post makes it sound like you suspected you did not do a good enough "clean install".

Do you have the R2R version you are trying to use blocked by your firewall? I checked on another site and with over 100 downloads, there is not a single comment about it...meaning no problems with the release itself. It should not be time bombing out on you. So you are left with either firewall settings or the actual pre-install cleanup you did.

For manual cleaning, try deleting, before re-installing clean:
C:\Users\<YourUser>\AppData\Roaming\Native Instruments\Komplete Kontrol
C:\Users\<YourUser>\AppData\Local\Native Instruments\Komplete Kontrol
and check here for any leftovers: Check C:\ProgramData\Native Instruments\

Registration Error: Unknown Serial
https://support.native-instruments....60005345538-Registration-Error-Unknown-Serial

Reset the Native Access XML file
Native Access relies on an XML file for product activation. If the NativeAccess.xml file becomes corrupt, this can cause the error message. You can safely delete the XML so that Native Access can create a new one.

1. Quit Native Access and all other apps.
2. Go to the following location of your computer:
   
   macOS: Macintosh HD > Library > Application Support > Native Instruments > Service Center
   
   Windows: C: > Program Files > Common Files > Native Instruments > Service Center
   
   
3. Delete only the file named NativeAccess.xml from the Service Center folder.
4. Relaunch Native Access and try entering your serial number again.

 

if you are running cracked Komplete Kontrol, you shouldn't need Native Access at all. With a legit version, you need to activate with it, but after that it is safe to delete. If I was running a cracked version, I'd want to get rid of Native Access, if possible. Just like Arturia's software manager, Native Access could be working against you, and possibly be the reason why it is deauthorizing R2R's release.

 

Perfect recommendations - I will execute them all and see what happens. Happy after Christmas by the way.

 

Unfortunately, did not do the trick. After every 2,3 or 4 restart of the programm the Demo mode returns for no apparent reasons :-( I do not have that issues with other Native products registered using the R2R approach though.

 

HOW TO SET UP YOUR KOMPLETE KONTROL KEYBOARD
www.native-instruments.com/en/specials/komplete/komplete-kontrol-setup/

What to try
1. Full cleanup of Native Instruments traces
2. Uninstall Komplete Kontrol and any NI products with their installers.

Manually remove NI folders in:
C:\ProgramData\Native Instruments
C:\Users<YourUser>\AppData\Roaming\Native Instruments
C:\Users<YourUser>\AppData\Local\Native Instruments

VST/VST3 plug-in folders:
C:\Program Files\VSTPlugins
C:\Program Files\Common Files\VST3)

REGISTRY ( Regedit) Search for Komplete Kontrol
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Native Instruments
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Native Instruments

Clean license data
- Delete or reset the NI License Center/Service Center databases if present.
- Remove any lingering license files for Komplete Kontrol specifically.

Reinstall from a clean source
Install Komplete Kontrol and then run Native Access to install required components (do not copy over remnants from prior installations).

Then restart your PC!

First launch sequence
1. Open Komplete Kontrol in standalone mode to allow it to build its internal database and cache.
2. Then rescan your DAW’s plugin folder and ensure KK appears as a valid plugin (VST2/VST3/AU as appropriate).
