Hello
I just went to the download page to get the 4.5.1 version. The instructions say to " [size=x-small][font='Open Sans', Tahoma, Verdana, Arial, sans-serif][size=small]Please choose “Windows, offline, 64bit” if you are on a 64bit Windows"   but i don't see an option to download that one.   Suggestions?[/size][/font][/size]

Oops... the sentence was referring to Java... not LRTimelapse.

Exactly, the LRTimelapse installer is always the same. If a 64bit Java is installed (recommended), LRTimelapse will run in 64bit.
