Sure, installation folders are fine. Both versions install together. And both run on startup. And i think it is not correct. Then if i uninstall 32-bit version even without deleting preferences - it still cleans up some usefull settings for x64 version like files associations etc. x64 installer cant kill x32 running process with Access denied error. Though it works good with running x64 version when re-installing. And those who will migrate from x32 version to x64 one (after stable release) surely will need it to work fine (able to kill x32 running process - simply launch it's uninstaller before continuing x64 installation) if we want it go smoothly My icons of x64 version seem to be fine...
