IE8 from 64 bit to 32 bit change -win 7

Having proplem with some sites, have a new desktop (1 week old Compaq, 500 gb SATA HD, 3 gb RAM, ATHLON 2.9 MHZ Processor) win 7 - 64 bit, have a 32 bit on the HD too, using IE 8, Dont won't to shift to Firefox right now would like to learn how to switch between the 32 bit and 64 bit in IE 8 browser.. had no problem until a paid cardsite I use wanted me to download a flashplayer. Didn't work. Can somebody help me with this. Any help appreciated, please excuse typos getting used to new keyboard too, liked the old one better, but it's toast...................sigh

 

I will try to do that Halo, but am also having problem with icons staying in the taskbar.

When I booted today all the settings there were gone, even as the bar was locked.
Do you know why. Doesn't windows remember the settings, it did in my XP ??
Thanks' very much
Also the cookies I keep in CCleaner don't seem to work, I have to sign into MG every time even though I have a cookie saved there.

 

Thanks so very much Halo what you suggested with the 64 bit and 32 bit works just fine. I have them pinned and have just named one 32 bit, the other one being the 64 bit from programsx86. And I can now get to my paid ecard site. Very important for me...............

I'm still not sure why the os doesn't keep the taskbar settings. Any ideas keeping in mind I have just had win 7 os for about a week ?
