sql server configuration manager says it is on a 32 bit machine and it is not. Should we change that?
It is misleading and according to some post it is a bug. You cannot change it.

Here is the connect item.

  It turns out that the label is very confusing.  There is a bug filed
  on it in the SQL bug database and it will hopefully get fixed in the
  future to make this clearer.  It turns out that this field shows if
  you are running a 32-bit version of SQL under a 64-bit OS (as in WoW).
  I had an X64 machine here with a 64-bit instance of SQL and a 32-bit
  instance of SQL.  The field shows "No" for the 64-bit version of SQL
  and "Yes" for the 32-bit version of SQL.  A bit misleading, but
  "correct" if you look at it in this way.  :)
