Installing the License key

Place email attached license file(s) on a USB drive at the root. Not in any subfolder. The USB device must be formatted with FAT32. Any other files on the device will not affect the installaton.

Exit the Tagpresto app if it is running. Insert the USB device into any USB port on your label printer. Launch the Tagpresto app again. Now the license key will be noticed and moved to your label printer. The license file will be automatically deleted on your USB drive after this process.

If you still see the free version, then restart Tagpresto. If that doesn’t work either, turn off your label printer by pressing the power button. Remove the USB drive and wait a few seconds. Press the power button again to boot. Then start Tagpresto again. Accept the EULA, by scrolling to the bottom followed by pressing Enter (middle navigate button) , if not already done before.
