Download and Install XLS Padlock
On our website at https://www.xlspadlock.com/download, you must select the installer that matches your version of Microsoft Excel (32-bit or 64-bit). The installer will verify that you are installing the correct version.
After a successful installation, XLS Padlock is integrated directly into Excel, appearing as a new tab in the ribbon. To use XLS Padlock, you must first open your Excel workbook.
Two shortcuts are also created on your desktop: one for this user guide and another for the XLS Padlock Manager.
