Oracle TranslationHub neither supported for 12c Database, 12c Forms/Reports or 64 bit!
If you need TranslationHub (Windows only) for your forms and reports development please immediately stop if you plan to move to one of the these
TranslationHub 11g is only available as 32 bit - requires Forms and Reports 11g too in 32 bit for Development
I have done the whole may scripting silent installs of several developer tools. Among them was Fusion Middleware 11.1.2 Forms & Reports. I see that oracle certifies the 64bit installers on win7 64bit and so I have successfully script this after a lot of time. I want not speak about the many errors in silent installers here. But what if you want to use TranslationHub too?
