Why not upgrade to 64-bit Excel?  (Your email address
suggests Georgia Tech?)

You can use GLPSOL to generate the problem in CPLEX LP
format and then feed that to another solver:

    http://en.wikibooks.org/wiki/GLPK/Interoperability
    http://en.wikibooks.org/wiki/GLPK/Interoperability#GLPSOL_usage
    http://en.wikibooks.org/wiki/GLPK/Interoperability#CPLEX.C2.A0LP_format

The call is:

    $ glpsol --check --wlp model.lp --math model.mod

GLPK can also tackle the same file:

   $ glpsol --lp model.lp

If you encounter problems, you could also try bridging
with the MPS free format.  Described in the above links.

You might also find something useful here, particularly
if you are coding in C, Java, or similar:
