Dear NAMD users,

I work with NAMD 2.9 on a Window7 platform and have used it for MD simulations. Upon using the NAMD Energy to measure the interaction. I clicked the "Run NAMDEnergy" and got a message that:
"Program not found
Could not locate 'namd2'
Description: NAMD 2.x Molecular Dynamics Engine
Would you like to specify its path?"

If I do not specify the namd file I get "Error: couldn't execute "": no
such file or directory"

When I do specify the namd2.exe file in \NAMD_2.9\, I get an error
"Error: Processor 0 exiting: Called Cmi Abort
Reason: FATAL ERROR: UNABLE TO OPEN .psf FILE I:��ResearchSnapshots and datasnapshots and dataSnapshotsfilename?pcl rial_8Energyfilename.psf

    while executing
"exec $namdcmd ${jobname}-temp.namd > ${jobname}-temp.log"

      variable nsel
      set energy ""
    invoked from within
".namdenergy.gobutton invoke"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 [list $w invoke]"
    (procedure "tk::ButtonUp" line 24)
    invoked from within
"tk::ButtonUp .namdenergy.gobutton"
    (command bound to event)"

What should I do?
Thanks for the help
