On Japanese Windows 7 64-bit (Home Premium SP1), N++ 6.3.3 always crashes immediately upon opening. See the original troubleshooting discussion here: http://portableapps.com/node/37203 It has nothing to do with PortableApps - in both the PA wrapped version and the regular one, 6.3.3 always crashes and 6.3.2 is fine. I tested the exact same copy of the program (from http://download.tuxfamily.org/notepadplus/6.3.3/npp.6.3.3.bin.zip) on four computers: it ran on English Windows 7 and Japanese Windows XP (32-bit SP3), but failed on two Japanese Windows 7 computers. A screen capture of the message is attached - although it's Japanese, it's the standard message that comes up when a program crashes: "A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available." At someone's suggestion, I tried deleting the Hunspell directory, but that had no effect on the problem.
Feel free to contact me if you want me to test a possible fix.
