como puedo cambiar mi programa ilustrador en español?

[#2 · Accepted solution]

Is it a CC version? Or earlier?

If it is CC and if your operating system is a different language than Spanish, then you need to uninstall the language you have now and then change the install language in the Creative Cloud app settings to Spanish. Then install. If your OS is Spanish as well, then you don't need to uninstall Illiustrator first. Just change the install language and then install.

Hi, you can change it from the apps in the creative cloud management application.
