If you see the orange exclamation mark, it means that the version of Grafcet Studio you have installed on your PC is out-of-date and you need to install the current version.
Click on the icon to open the Update Dialog. You can download the current installation program from here.
Close Grafcet Studio before you start the installation program.
You do not need to remove the current version before you install the new one.
In the update dialog you can also see whether your license is valid for the new version. After purchasing the software you can 1 year long always use the latest version. If you always want to use the latest version after this year (we recommend that you do so), you can purchase an affordable subscription. Before the initial subscription expires, you will receive an email reminder so that you can renew your software subscription in time.
