When you connect to the Microsoft Windows Update Web site by using the 64-bit version of Microsoft Internet Explorer, you receive the following message:
Thank you for your interest in Windows Update
We need to open a 32-bit version of Internet Explorer
You can still install updates for your 64-bit version of Windows. However, you need to use a 32-bit version of the browser to view the website.
If you click Open it now, the 32-bit version of Internet Explorer opens, and Windows Update continues. The following message appears in the 64-bit Internet Explorer window:
Thank you for you interest in Windows Update
Please close this browser window
A 32-bit browser is now displaying the update website.
This behavior occurs because Windows Update uses 32-bit ActiveX controls. Therefore, Windows Update requires a 32-bit browser to work correctly. If you access Windows Update by using the 64-bit version of Internet Explorer in x64-based versions of Windows, you receive the message in the "Symptoms" section. The 32-bit version of Internet Explorer is started and opens the Windows Update Web site.

Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your Windows x64 edition. However, you might have to contact your manufacturer directly.
