Hello spsaarathi and welcome to the forums

What language are you using for IE9? I've got all of your replacement files apart from two which depend on your language pack

Hello Tom,
Thanks for responding to my post. I do not use any language pack for my IE. It is a standard version ENU.

Thanks in advance

Hi Tom, Thanks for your help.
I was not shown error code 0x8024200D after performing this fix. Please find the requested file attached. My IE9 instalation also failed.

Best regards

Hi Spsaarathi,

It looks like the SURT has performed the replacements without any issues, so there's no problems at that end. What error code were you shown when IE9 failed to install?

Tom

Hi Tom,
Sorry for late reply. Thanks for your response.

Windows 7 sp1 installed successfully but IE9 failed to install. Currently IE8 is installed in my PC.

Thanks in Advance

Hi Partha,

I'm glad to hear that, I was half expecting IE9 to fail after that fix. Fortunately, this fix is a lot easier, just download and install it from the web:

Download Internet Explorer 9 - Microsoft Windows
