I`m an subscriber to adobe CC and I installed all apps in english except Indesign CC which is in Korean.
So When I need to update Indesign, I should change the language of Creative Cloud from EN to KOR.
But, the button which is able to change language has been greyed out. So, I cannot choose it!
I need your help!
Joowon, please try to sign out from Creative Cloud and sign back in. You may also try the following steps to update your product.
1. Launch InDesign CC2015.
2. Click on 'Help' > 'Updates'.
Hope this helps.
