IllustratorGc.jsx script error while launching Illustrator 25.3

I have the same problem with my macbook pro... please i need help i cant use illustrator, i upgrade de logi app. 

I have also tried to update the ltest version for Logi Option, but the warning still popup every 30 Seconds.

but the following steps works for me: 

open logi option, choose the device - go to All Applications - Disable Application Specific Setting.

hope this would help for now until the next AI or Logi Option Update.

I have had this error for a week and I have Logi Options installed for my MX 3 Mac mouse.

Having read a few threads, I have managed to fix using the same process for Logi Options issues in Photoshop.

Open Logi Options, navigate to the 'All Applications' tab, from the drop down list do either of these;

If Illustrator is missing add it to the list, then open Illustrator, this was my problem and once added its fixed the script issue.

If Ilustrator is listed, delete it (first make a note of customisations you have set up, as you will need to put them back afterwards). Open and close Illustrator, go back to Logi Options and add Illustrator back (plus any customs keys), again it should be fixed.

There have been many issues with Photoshop for months with Logi Options until somone tried this simple fix, it works for most people with Photshop looks like it could do the same with Illustrator.  Logitech cleary have problems when upgrading and linking to Adobe products, this process clears out unwanted Logi Options files and puts new ones back in the right places. Takes 5 mins to give it a go!

This should not be marked at solved.

Updating Logi Options to the latest version does not work.

Any chance of an actual explanation as to why this occurs? Or an actual solution on Adobe's part?

Downgrade the ai to version 25.2.3 works for me

I think I figured it out! No amount of updating or uninstalling worked. However, in Logi Options, the box for "Create custom settings for specific applications" was enabled by default. I toggled off the button for Application Specific Settings, and the annoying notice is gone in Illustrator. 

I have the same thing! It has made design nearly impossible. I updated the app for my Logi mouse and the fix didn't work. I restarted the computer. Still an issue. I'm going insane!

Hey all,

So I just fixed this error by manually downloading an update for Logi Options via their website. It sounds like many of you have the same issue in that the app says "No Software Updates" when you search for them. However, if you go here:

https://www.logitech.com/en-in/product/options

Then click:

"Looking for another version?"

It will smart search what you need and hopefully offer an update like it did me. After installing and restarting my computer, I have not had this error.

Best,

Jason
