IllustratorGc.jsx script error while launching Illustrator 25.3

still got the problem in 2025!

For those that are not familiar with code, I have done that an Works (MACBOOK PRO):
1) Install a code editor like Visual studio Code (Free).
2) Type this:
app.preferences.setBooleanPreference("ShowExternalJSXWarning", false)

3) Save it on desktop as .jsx (write this at the end).
4) Go to illustrator and do that: File > Scripts > Other Scripts

Hopefully that helps!

Hi there,

One easy fix is to simply drag the dialogue box out of your visual workspace. This way you can still use the crown without the warning screen popping up every time you try to use it. However, you will have to close the warning box if you are trying to save or exit the program, as the program prioritizes the warning box over the main menu functions. 

P.S. the .jsx file did not eradicate the problem for me, so i have been using this method

This is so damn annoying, literally shouting at my computer here.

I'm glad the workaround helped with the javascript. 

Still having this issue on Illustrator 25.4.1

This is VERY annoying. I tried making my own JSX file to diable the popup as mentioned by rama_ai but it doesn't work.... I copy pasted exactly what was in the message: app.preferences.setBooleanPreference("ShowExternalJSXWarning", false);

But when I import the .jsx file Illustrator says there is a syntax error?

We are investigating this issue and reached out to Logitech for permanent solution. Meanwhile users can try the below workaround.

Create a JSX file with the following content:

app.preferences.setBooleanPreference("ShowExternalJSXWarning", false);

Save the above JSX file. Now, go to File > Scripts > Other Script, and choose the newly saved jsx file.

This will suppress the warning dialog and run the script.

I also have the issue despite having updated everything. Waiting from a prompt solution from adobe

thanks
