Install wizard for 24.8.2.1 failed when I tried to update 7.4.5.1

I have Windows 10 and have used LibreOffice for several years. I attempted to update to 24.8.2.1 and the install wizard tried to install … failed when it got to the end making the shortcuts for each component and then rolling back actions states “The wizard was interrupted during installation … Your system has not been modified. To complete the installation at another time, please run setup again”

the install or rollback removed the old version (7.4.5.1) … running setup again results in the same failure points and I no longer have access to several password protected documents. I am at a loss to how to proceed at this point
