If you have downloaded the Adobe CC or CS6 Master Collection trial and it isn’t installing in English, then it might be a Region and Language settings problem.
Here are the steps to fixing the problem, if this is the case:
1. Open the Control Panel.
2. Open Region and Language settings.
3. On the Region and Language window click on the Formats tab. Then change the format to English.
Eg. Format: English (United States)
4. Try installing the Adobe CS6 Master Collection trial again.
It should now install in English ^^
