What happens to my license if I upgrade Photoshop to a newer version?

You can continue using the product without interruption by following the procedure below that matches your version of the plugin.

If you installed the product by file copy (versions 1.0 to 1.0.2[file version]).
Delete manually the previously installed plugin, then, after installing the new version of Photoshop, re-install the plugin using the latest version of the installer.
*Plugins installed by file copy cannot be uninstalled by using the uninstaller.

If you installed the product using the installer (Version 1.0.2[installer version] and up).
Uninstall the previously installed plugin, then re-install it after installing the new version of Photoshop.

In both cases, it is necessary to input the license key once more after re-installing the plugin.
At that time, if the machine code is different from what it was when you last installed the product, you will need to re-authorize it.
You can download the latest version of the installer from the user page.
