I've updated to version 4, but I cannot get LastPass to work using IE 64 bit. It always used to work but I don't really want to reinstall an older version should that be even possible. The icon is present, but is greyed out and clicking it doesn't accomplish anything. It works fine using FireFox and IE 32 bit. (If I double click the desktop icon, it starts IE 32 bit, so that works).
The addon is enabled and I can't see anything awry in settings. Is there an IE 64 bit specific addon? or a step I'm missing?
