Fellow I have just downloaded the Windows 7 64-bit RC. I used the Deamon Tools and mounted the ISO file of Win7 RC and copy its contents to a Harddisk. Previously I was using Vista 32 bit & not when I click the setup a message pops up saying "The version of this file is not ompatible with the version you are running & check whether you need 64 or 32 bit." Please tell what is the pronlem now.
