First of all, do not download Microsoft files from third-party sources. Use only the MS download site:

Make sure you choose the correct language version, also have a look at the requirements, most importantly: Are you sure you have the required version of the Windows Installer? Install the installer first:

Then, checking your posted log file makes it evident that it does not contain detailed information on the failure; two more log files must exist with further info:
- Microsoft .NET Framework 4 Setup_20100930_122736879-MSI_netfx_Extended_x64.msi.txt
- dd_SetupUtility.txt
Just open the log file you posted on your system, then click the links in the log. Then post the additional logs here, please.

please tell me the solution , can i able to install .net framework 4.0 on window 7 or not ?
Please do not impose pressure: I am not a service desk employee here, I have my own work to attend to.

I tracked it down to the following error:
"MSI (s) (2C!3C) [12:29:41:209]: Product: Microsoft .NET Framework 4 Extended -- Error 25003. Error occurred while initializing fusion."

When checking for fixes, one ends up on this tech blog where an admin explains how to install .NET 4:

Please scroll all the way down: it guide ends with the same error. That was yesterday. So far, no fix was found.
I suggest you bookmark that page and check it once a day until a fix is posted.

On a side note:
Personally, I'd never volunteer to install a .NET framework on any of my systems. Too buggy, too many risks, too much headache. Framework 4 is new, so even more of all that may be expected. Only install if absolutely required by a program and no alternative program may be found, otherwise enjoy your system with one of the older frameworks that actually work and install.
