For those who are using Windows 7 and experienced problem with Khmer Unicode (NiDA keyboard), for example you are unable to add its keyboard into Language bar or to type Khmer Unicode on Microsoft Word, you now have no worry about that problem. With Khmer Unicode version 2.0.1, it works good enough on all types of Windows, particularly Windows 7.
I tested on my laptop which is using Windows 7 Home Premium, and it works fine, but not perfectly due to some error, for example when I type in the search box on Windows Explorer, it shows square box. I will test it on other PC. However, it is the best choice for the time being.
