Unfortunately, the versions listed on the official website are compatible only with Windows 7. I've tried to install that version of Windows 10 but it gives an error regarding the Java installation.
I do have JDK and JRE installed and running without errors but somehow Geotrans fails to detect them. I've also used compatibility methods and the result was the same.
Because of this, I must say that Geotrans isn't compatible with Windows 10.
