Windows – Internet Explorer 9 update fails on Windows 7 64-bit

This not the first such question I am answering here. Internet Explorer 9 seems to be unable to install itself on some computers.

Seeing the number and variety of attempts that you have already done, there is not much left. "Use Software Rendering" is almost always cited as the reason for startup crashes, but you have tried it already, but better keep it checked for future tests, as well as using no add-ons.

EDIT: See this Microsoft article: How to solve Internet Explorer 9 installation problems.

Questions:

1. Did you look into the Windows 7 Event Viewer?
   An error entry there from when it crashed might point us in the right direction.
2. Did you specify any non-standard paths when installing Internet Explorer 9?

If a cause cannot be found, then the only solution would be to uninstall Internet Explorer 9 and wait for the service pack.

How-to reset the File System Resource Manager if you receive error 0x80071A91

1. Click Start click All Programs click Accessories, right-click Command Prompt, and select Run as administrator.

2. In the Command Prompt window you will need to type the following: fsutil resource setautoreset true C:\ and press ENTER

3. Note: You will need to replace the C:\ with the drive letter that Windows 7 is installed on.

4. Restart your computer, and then attempt to install the failed update(s).

As always you can try the Microsoft FixIt Tool.
