Fiji on Windows 10 won't launch with Korean characters in the path

[gyuregor]

I just downloaded the newest Fiji version from the site. I have up-to-date Java 8 running on a 64bit Windows 10. When I double click on the exe, only the Fiji splash icon appears and then nothing happens. When I debugged, there were descriptions below. What should I do?

@gyuregor I have not seen this particular error before. It suggests that perhaps your installation of Fiji is incomplete. Is the file C:\Users\조규찬\Desktop\Fiji.app\jars\imagej-2.0.0-rc-69.jar present, with file size 10194 bytes? That JAR file is where the net.imagej.Main class lives.

A stab in the dark, but if the installation is complete, could be the Korean characters in the path?

imagej-2.0.0-rc-69.jar is present at the right place with size 10194 bytes....

Korean characters are present in the path, because I set my user name in Korean characters. Could it be the problem?

[rimadoma]

It is possible. Could give a quick try installing in a different folder, like "C:/Test/"

Fiji successfully runs just after I installed it in "C:/Test/" folder. Thank you so much for your advice!

@gyuregor I changed the title to reflect the problem. We can leave this issue open as a reminder to investigate and fix the problem in future. Thanks!
