So...I discovered that English Bandicam does not work on English Window
IF
Language setting for Language for non-unicode programs is set to Korean(Korea).
This makes Bandicam to think that my latop is using Korean Window, therefore, error message says download Korean bandicam...
I don't undertand why...and I don't know if there is even a solution to this problem.
I could download Korean bandicam, but technology terms will be in Korean, which will be difficult to understand. I can't switch the language setting to English because if I do that certain files with Korean names will show in broken korean.

what do i do?

Bandicam follows the Windows language setting.
In your case, you'd better use Korean version of Bandicam.
Please check your email for more information.

Thank you.
