MS-Office 2010 error 1935 during installation

I am trying to install MS-Office 2010 to my Windows Vista computer, but I am receiving error like this;
Error 1935. An error occurred during the installation of assembly component
And a long set of numbers which I could not understand. The installation did not finish successfully. I temporarily disable my firewalls and all thinking that something is interfering with the installation, but I have no luck.
What is causing this and How can I resolve this?
Please help.
