What is a license for more devices? One license that can protect several devices is available for purchase. During installation, you can type or copy/paste the same License Key into the number of devices you have purchased the license for.
You can manage your licenses and devices in ESET HOME. When you register in ESET HOME with the same email you used to purchase your license, the license is automatically assigned to your ESET HOME account.
Do I need to buy a new license to reinstall my ESET product? No, you can uninstall and reinstall your ESET product for troubleshooting purposes or otherwise at any time using your existing license.
You are only required to purchase additional seats if you plan to have ESET products installed and activated on more devices than your license covers at any given time.
Does reinstalling my ESET product use one of my licenses? No, reinstalling your ESET product does not affect your license usage. Your existing license remains functional for the duration of your subscription regardless of how many times you remove or install the product on the computer to which it is registered.
I bought a new computer / re-formatted my current computer. Do I need to purchase another license? No, you can download our software as many times as necessary. To reinstall your software, follow the steps in the following Knowledgebase article:
I want to use more than one ESET product. Do I need to purchase a license for each one?
If you purchase a license for ESET Smart Security Premium, you may use that license to download/install ESET Smart Security Premium, ESET Internet Security and ESET NOD32 Antivirus.
If you purchase a license for ESET Internet Security, you may use that license to download/install ESET Internet Security and ESET NOD32 Antivirus.
If you purchase a license for ESET NOD32 Antivirus, you may use that license to download/install ESET NOD32 Antivirus.
Purchasing a license for ESET Internet Security does not allow you to download/install ESET Smart Security Premium.
Purchasing a license for ESET NOD32 Antivirus does not allow you to download/install ESET Smart Security Premium and ESET Internet Security.
You should never install ESET Smart Security Premium, ESET Internet Security and ESET NOD32 Antivirus on the same system concurrently.
I use a dual-boot computer with two separate operating systems. How many licenses do I need? Each operating system counts as one device, so you need a separate license for each operating system or a license for more devices.
I use dual-boot software (for example, a Mac computer with Boot Camp). Do I need separate licenses for my macOS and Windows operating systems? Yes, you will need to purchase a license for ESET Cyber Security/ESET Cyber Security Pro and an ESET product for Windows.
I have multiple operating systems running simultaneously using virtual machine software such as VMWare, Citrix or Parallels—how many licenses do I need? A single license enables home users to install the standard home product on one physical machine. Each virtual Endpoint counts as a physical Endpoint (one license per virtual machine is required).
Why do I need a License Key? When you purchase a license for an ESET product, you receive an email from ESET containing your ESET-issued Username and Password. This email is delivered to the email address used at the time of purchase.
ESET has introduced a new License Key (previously known as Activation Key) that will eventually replace the need for a Username and Password. If your email from ESET does not include a License Key, you will need to convert your Username/Password credentials here to activate the latest ESET home products.
This conversion will not have any effect on your license. The License Key represents a unique string in the format XXXX-XXXX-XXXX-XXXX-XXXX which is used for identification of the license owner and activation of the license, as well as the license credentials.
Where is my Username and Password/License Key? After purchasing your ESET product, you should have received an email message containing your Username, Password, and License Key.
Someone else set up my ESET product. How do I transfer the license to my name? To transfer account information to another name, the person who originally registered the account needs to call or email ESET technical support with the following information: Name, email address or street address of the original account holder; the new name, address or email account that the license is to be updated with.
Can I extend (renew) my license before the expiration date? ESET does not currently offer a license extension program.
North American customers: You may renew any time after your purchase and up to 365 days after your license expires. If you decide to renew before your expiration date, your new expiration will not take effect until your original expiration date passes.
I just renewed, but my old expiration date is still displayed in the program—why? In some cases, users may experience a brief delay before the expiration date is updated and program updates are downloaded. Your virus protection will remain active, and your computer will be secure during this time. If you renew before your expiration date, your new expiration date will not take effect until your original expiration date passes. If more than 24h pass and the license is still showing as not updated, activate your product again with your license key.
How do I add, subtract or combine my previous licenses before renewing? Our Sales Support team will be happy to assist you. License modifications are allowed within 30 days of your initial purchase or 90 days of your renewal date. Use our contact page for further assistance.
I purchased a license for more devices. How many seats do I have left? Our update servers will only notify you when you attempt to update more devices than you have been allotted (you will get an error while updating).
What is ESET Multi-Device Security? ESET Multi-Device Security Home Office Edition?

What is ESET HOME? ESET HOME is a service introduced with version 14 of ESET home products that enables you to manage your ESET licenses for multiple devices or products from one location. Visit the ESET HOME User Guide for detailed instructions about how to use ESET HOME.
Can I use the same license to change to a different ESET home product with higher features? Yes. If the ESET home product license being used qualifies for a product with more features, "Your license allows you to install a product with more features" will be displayed after installation. The user can accept the product change or stay on the current product. The user can also change to a product with more features at any time.
