A successful antivirus installation begins before you run the installer. Check the product you purchased, the operating system on the device, and the account email associated with the subscription.

This simple check can prevent unnecessary repeated work.

Compare your device with the vendor's requirements for the edition you intend to install. Review the supported operating system, available storage, and any required updates. Save open work and complete a pending restart ahead of starting setup.

Once the application opens, check whether it recognises the subscription you intended to use. Installation and paid activation can be separate steps. A working app window does not by itself confirm a paid licence. Follow the account or activation directions shown for that edition.
