SafeDESIGNER Cannot be Opened

[arif.kaya]

Hello,
Even though I have almost all versions of the SafeDesigner program, it does not open.
What should I do ?

Thanks !

Hello Arif Kaya,

I think the safe designer V 4.4.0.0 is no longer available, all you have to do is to change to a version that is currently available in your pc.

To do so, right click on the safety plc in your project,

and in configuration, change the version.
