The default behavior of the LockXLS is to convert your workbook to stand-alone application. However you may decide to convert your file to the locked Excel workbook to keep the XLS or XLSM extension. This option requires to have the LockXLS Runtime installed on the PC. More information you can find in this topic: How to distribute my files to the customer's PC.
If you do not want your customers to install the LockXLS Runtime module, LockXLS can create Installation Package (MSI) with option Silently install LockXLS Runtime. This package contains all your files (workbooks, help files, etc.) and LockXLS Runtime Add-In. Setup silently installs LockXLS Runtime on the customer's PC and extracts all your files, which you've added to project.
