Question : SQL 2008 R2 setup support files failed on Win 2008 R2

I am trying to install SQL 2008 R2 on top of WIN 2008 R2 but I am facing problem which I have never experienced before. SQL Server setup detecting the processor as 32 bit while it is 64 bit (OS 64 bit also). when I reach setup support files it shows the following error:

Product: Microsoft SQL Server 2008 R2 Setup (English) -- Error 1935. An error occurred during the installation of assembly 'Microsoft.VC80.CRT,version="8.0.50727.4027",publicKeyToken="1fc8b3b9a1e18e3b",processorArchitecture="x86",type="win32"'. Please refer to Help and Support for more information. HRESULT: 0x800736CC. assembly interface: IAssemblyCacheItem, function: Commit, component: {98CB24AD-52FB-DB5F-A01F-C8B3B9A1E18E}

I tried it on 4 servers with the same model and type it worked only on one of them. Some people told me it is related to .Net framework. and I found some websites talking about corrupted VC++ components .I tried to fix it I couldn't. Any one can help me?

Answer : SQL 2008 R2 setup support files failed on Win 2008 R2

put this simple javascript after the closing html tag
<script type="text/javascript">
        function callMe()
        {
            if(Page_IsValid == true)
            {
                a = document.getElementById("divToShowID");
                a.style.display = "";
            }
        }
        Page_IsValid = false;
</script>

then set the OnClientClick="callMe();" of the button
