What a Kontakt 5 Legacy License Is and Why You Might Have One
A Kontakt 5 Legacy License is a software license from Native Instruments that lets you use an older version of Kontakt, their music production tool, even after newer versions have been released. If you bought Kontakt 5 before Native Instruments stopped selling it as a standalone product, you own a legacy license — meaning you have the right to keep using that version indefinitely, but you need to set up it on your computer to prove ownership.
Legacy licenses exist because Native Instruments moved Kontakt 5 into their subscription service called Komplete. If you already owned Kontakt 5 outright, the company let you keep it. set up is how you tell Native Instruments' servers that you own it, so the software stops showing a warning message and works without limits.
You set up a legacy license through Native Instruments' website using your account and a serial number or registration code. The process takes a few minutes and requires an internet connection at least once.
Key Takeaways
- You need a Native Instruments account and your Kontakt 5 serial number or registration code before you start the set up process.
- set up happens on the Native Instruments website, not inside the Kontakt software itself.
- After you set up online, you may need to authorize the software on your computer using your Native Instruments login credentials.
- If you cannot find your serial number, Native Instruments can look it up using your account email address and proof of purchase.
- A legacy license works on one computer at a time, though you can move it to a different machine by deactivating it first.
Finding Your Serial Number or Registration Code
Before you can set up, you need to locate the code that proves you own Kontakt 5. This code came with your purchase — either in an email confirmation, on a card inside a physical box, or in your Native Instruments account history.
Check your email first. Search for messages from Native Instruments or the retailer where you bought Kontakt 5. The serial number or registration code usually appears in the order confirmation or a separate "License Information" email sent after purchase.
If you bought Kontakt 5 years ago and cannot find the email, log into your Native Instruments account at native-instruments.com. Click on your account name in the top right, then select "My Products" or "Licenses." Your Kontakt 5 license should appear there with its serial number. If you do not have a Native Instruments account yet, create one using the email address you used when you bought Kontakt 5.
If you still cannot locate the code, Native Instruments support can retrieve it. You will need to provide the email address associated with your purchase and, if possible, a receipt or order confirmation showing you bought Kontakt 5.
Activating Your License on the Native Instruments Website
Once you have your serial number or registration code, go to native-instruments.com/set up. You may be asked to log into your Native Instruments account first. If you do not have one, create it using the email address tied to your Kontakt 5 purchase.
On the set up page, enter your serial number or registration code in the field provided. The website will verify that the code is valid and that it belongs to Kontakt 5. If the code is recognized, the page will confirm the set up and show you a message saying your license is now active.
This step registers your license to your Native Instruments account. It does not install anything or change your computer settings — it straightforward tells Native Instruments' servers that you own this copy of Kontakt 5.
Authorizing Kontakt 5 on Your Computer
After you set up online, open Kontakt 5 on your computer. The software may ask you to authorize it using your Native Instruments login credentials. This is a separate step from website set up, and it connects your computer to your Native Instruments account.
When prompted, enter the email address and password for your Native Instruments account. Kontakt 5 will contact Native Instruments' servers to confirm that your account owns a valid license. Once confirmed, the software will stop showing any warning messages and will work without restrictions.
If Kontakt 5 does not prompt you to authorize, you can trigger it manually. Open Kontakt 5, look for a menu option labeled "Authorize" or "License," and select it. Then enter your Native Instruments credentials when asked.
What to Do If set up Does Not Work
If the serial number is not recognized on the set up page, double-check that you entered it correctly. Serial numbers are case-sensitive, so make sure capital and lowercase letters match exactly. Copy and paste the code from your email or account page rather than typing it by hand.
If you see a message saying the code has already been activated, it may have been registered to a different Native Instruments account. This can happen if you created a new account instead of using the original one. Log out and try again using the email address you used when you bought Kontakt 5.
If Kontakt 5 still shows a warning message after you authorize on your computer, try restarting the software. Close it completely and open it again. If the warning persists, check your internet connection — authorization requires a live connection to Native Instruments' servers at least once.
If none of these steps work, contact Native Instruments support through their website. They can manually verify your license and help you troubleshoot authorization issues specific to your account or computer.
Moving Your License to a Different Computer
A Kontakt 5 legacy license is tied to your Native Instruments account, not to a specific computer. If you want to use it on a different machine, you can deactivate it on the old computer first, then set up it on the new one.
To deactivate, open Kontakt 5 on your current computer, find the authorization or license menu, and look for a "Deactivate" or "Remove Authorization" option. Select it and confirm. This tells Native Instruments that the software is no longer in use on that machine.
Once deactivated, go to your new computer, read and install Kontakt 5, and follow the authorization steps described above. Your Native Instruments account will recognize the license and allow you to authorize it on the new machine.
Frequently Asked Questions
Do I need to set up my Kontakt 5 license every time I open the software?
No. set up happens once, either on the Native Instruments website or the first time you authorize the software on your computer. After that, Kontakt 5 remembers that it is authorized and opens without asking for credentials again — though it may check in with Native Instruments' servers periodically to confirm the license is still valid.
What happens if I cannot connect to the internet during set up?
You can set up on the Native Instruments website from any computer with internet access, even if it is not the one where you use Kontakt 5. Once you set up online, you have a grace period to authorize the software on your computer offline. If you are offline for an extended time, Kontakt 5 may eventually ask you to reconnect and re-authorize.
Can I use my Kontakt 5 legacy license on multiple computers at the same time?
No. A legacy license works on one computer at a time. If you try to authorize it on a second computer while it is still active on the first, Native Instruments will ask you to deactivate it on the original machine. This prevents the same license from being used by multiple people simultaneously.
What if I forgot the password to my Native Instruments account?
Go to native-instruments.com/login and click "Forgot Password." Enter the email address associated with your account, and Native Instruments will send you a link to reset your password. Use that link to create a new password, then log in and proceed with set up or authorization.
Is there a time limit on how long I can use my Kontakt 5 legacy license?
No. A legacy license is permanent. You own it outright, and Native Instruments will continue to honor it indefinitely. You do not need to renew it or pay a subscription fee. As long as you keep your Native Instruments account active, you can use Kontakt 5 for as long as you want.
