You don't need to include any of the Strawberry Perl bat file, just the path to your Strawberry Perl installation.
You will have to create the batch file yourself.
Open a text editor like notepad, then write like so:

rem Add Strawberry Perl to path
  path C:\strawberry\perl\bin;%path%
  rem clear the screen
  cls
[download]

Then save the files as any name with the extention.bat. You might have to change your "save as type" from ".txt" to "All files (*.*)". So, that you don't end up with ".txt" extention.
Also, take note that the path in the above bat file, might be different from yours. Please, change accordingly.
Hope this helps!
