I also get a crash with 801 under win64. I had 701 installed on this machine, and had installed the 801 beta several weeks or months ago. I uninstalled both of those versions on this machine, and then downloaded and installed the new version of j801/j801_win64.exe dated Feb 25.
The installed jqt shortcut crashes immediately when I click on it.
