Can someone explain to me what the differences are between Internet Explorer 9 32bit and 64bit versions? I have a 64bit machine but always just use 32bit IE9. What are the benefits if any of the 64bit version?
I find that IE9 64bit opens much faster on my Windows 7 system.
Yeah from what i gather the 64bit version handles processes a lot faster etc but on the downside plug-ins like Flash do not work properly.
You need the 64bit Flash plug-in.

I wish Adobe would support Flash on 64bit systems better. :
