Sql-server – SQL Server install on 64 bit Windows 7 installing as 32 bit

64-bitsql serversql-server-2008

I am attempting to install SQL Server 2008 R2 on a new 64 bint Windows workstation.
I wish to install the 64 bit version and am using this iso file:

en_sql_server_2008_r2_developer_x86_x64_ia64_dvd_522665.iso

But it has repeatedly started installing the the 32 bit (x86) version.
I cannot figure out how to get the installation process to install the 64 bit version.
What am I doing wrong?

When I've run into that it's been because the installer detected previously installed 32-bit SQL components. In my case I was able to just blow out the 32-bit components and reinstall the 64-bit.
