I have installed Oracle Client 12c Release 2 on my windows.
I want to change its language to Japanese, not English.
When I have some errors, I would like it shows error in Japanese.
I have set Region, language, datetime format before the install and installer shows in Japanese but then after finised, my code still shows messages in English. Installer have no choice for which language I would like to install product.
I have search google for this problem but I have no idea. Some people told me to change NLS value but I can't find it in regedit because it is oracle client not oracle database home (i think so).

Please help me, thank you so much.
