why is your product not installing like every other product I've used for 20 years

no details I downloaded a .man file --need .exe file


-1 because question is not constructive. Constructive would be something like, 'How do I install LibreOffice?"

there is a .msi installer for windows, Download LibreOffice | LibreOffice - Free Office Suite - Based on OpenOffice - Compatible with Microsoft

You used Internet Explorer, which is notorious at mangling MSI files into MAN files. Not a first time we’ve seen this.
