Hi Vinay,

   The chimera-1.2422-linux_x86_64.exe distribution is for 64-bit
versions of Linux.  If you are using a 32-bit linux (even with a 64-bit
processor) then you need chimera-1.2422-linux.exe instead.

   If that is not the problem, could you be more specific about what
goes wrong when you try to install?  What is the error message?
