problem in installing glpk and gurobi solver

[Sharman]

earlier the pyomo and glpk were working properly in my system (windows 7,32bit,python 2.7.10 ,glpk 4.55) but suddunly i got a message that :

No executable found for solver 'glpk'

i tried the same thing earlier i did for installing glpk by copying all dll and exe files in python directory ,but i didn't work.

then i set glpsol in environment path but still getting the same error for glpk. for GUROBI(academic addition ) it's showing some licence issue and not executable.

any help would be appreciable.   

[David Woodruff]

The important test for glpk as a solver is to give the command

glpsol --help

followed immediately by a pyomo command that uses glpsol (with cd in between).

If gpsol works, but pyomo does not, please send a screen shot of the session with the two commands.

Thanks,

   Dave
