Excel requested even if already installed


One of my user has this problem: he tries to launch the .exe workbook and the following message appears: “Excel is required in order to run this application. Cannot continue.”
He has a new computer with Windows 10 pro 64bit and Excel 2016 32bit installed.
What’s the problem?
I have created the workbook with XLS padlock 2.4


By default, secure applications made with XLS Padlock detect Excel thanks to the Windows registry:
Open RegEdit, navigate to HKEY_LOCAL_MACHINE > SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\excel.exe

Ask you user to double-check that the path to the Excel’s EXE file is correct. If it isn’t correct, he’ll have to fix it or repair Office so that the path is correctly set up by the Office’s installer.
