You need to extend the 'path' environment variable so that it includes the folder where you installed CRYSTALS, e.g.

path=c:\wincrys\;"%path%"

set crysdir=c:\wincrys

Take care with the symbols - get it wrong and you may need to re-boot!

You can also edit AUTOEXEC.BAT to include these lines so that CRYSTALS is automatically available when you open a DOS BOX.

To run CRYSTALS, change to the directory containing the data for the compound and type:
