Although slightly different, after trying several different
variations, this seems to work for me:

on mouseUp
   set the defaultFolder to "C:\crc32\" --> must set the folder
location to the same as crc32.exe
   put "crc32.exe" into tCommand
   put " readme.txt > c:\crc32\output.txt" into tArg
   put tCommand & tArg into tShellText
   get shell (tCommand)
   get URL "file:c:\crc32\output.txt"
   put it
end mouseUp

Note the importance of setting the folder path to the location of crc32.exe
