Why is the EXE file so large?

The size of the .EXE file is expected because XLS Padlock produces stand-alone EXE files that must work with different Excel and Windows versions. They also use full Unicode support, VBA interpreter and this has a “price” (large size).

Finally, EXE files have got anti-piracy protection which contributes to the size too.

If you don’t use our advanced protection features, you can disable formula protection and you’ll get a smaller EXE file.
