I have win7 64bit and cannot get javascript.
I follow all the instructions and check them all as required except one.
It says to allow "paste operations via script" but I do not see that under security, custom, script heading. I see the others, but not that.
Can you tell me what to do to get javascript or where to find the "paste operations, etc." settings?
Thanks.

Please provide a link to the instructions you are following.

My guess is your using internet explorer 64 bit ? If so just pick up another browser like chrome or Firefox or internet explorer 32 bit. That way you can have both flash and java when needed.
