Hi,

Is there a way to install offline PLC Opta IDE ?

I got some industrial computers which can't be connected to internet.

In other hand, I can copy some files from a computer where PLC IDE is installed.

i'm thinking about device definition files which are downloaded during installation.

I tried to copy and paste "T" folder (from an connected computer) and then run installation file but didn't succeed !

HI @kalain !

You may try to download the two files and store them on USB Disc or Stick:

(Scroll down to **Arduino PLC IDE 1.0.3)**

If it works you need to activate the IDE manually:

See [https://docs.arduino.cc/software/plc-ide/tutorials/plc-ide-setup-license/](https://docs.arduino.cc/software/plc-ide/tutorials/plc-ide-setup-license/)

(Scroll down to **Offline Activation)**

Good luck!

Thanks for the tip 👍 but unfortunately "Arduino PLC IDE Tools1.0.3" needs also internet connection for a proper installation !!!

So, I think I will manage with an USB Wifi key.

Why not to include all files in .exe installer in order to install it on non connected computers !!!
