Cannot Update LibreOffice

I recieved a notification within LibreOffice that I needed to update LibreOffice manually from the website, so I downloaded the installation file (I’m on Windows 10) and attempted to reinstall the application over my current installation so I could update it. However, even though I am the administrator (That is, the only user) on my system, and I granted all permissions the installer asked for, it encounters an error during the “copying files” phase of installation. The error says Error 1303: Insufficent priveleges to access this directory C:/Program Files/LibreOffice/Program. The installation cannot continue. Log on as an administrator or contact your system administrator.

In addition, the original copy of LibreOffice has been deleted from my system. I’m an active writer working on a project and now I can’t work. An immediate solution would be greatly appreciated.
