Unable to install in Windows 10: "Insufficient privileges"

I was using LibreOffice when it updated to the newest version (6.1.3) when it encountered a problem and said the installation failed as there were insufficient privileges and telling me to log in as administrator or to contact my system administrator. This is my personal computer; I’m the only one who uses it, and my account is the administrator account. After the installation failed, I found that there was no Libreoffice functionality on my computer at all; the old version had been uninstalled. I tried to reinstall version 6.0.7 but that wouldn’t work either. How can I get Libreoffice back on my computer? I need it for many personal projects.

Do you run any antivirus that could prevent the installation? Check your login to see if you are an admin?

Check the Windows Event Viewer for errors regarding the installation.

Also, are you using Defender?

Well, it seems to have resolved. I shut down the computer and came back the next morning, and gave it another shot to see what would happen, and it loaded and installed with no problem. I don’t know what happened but it’s working now. I guess I should remember that for future issues.

For any others who search on this question, it would be helpful to note that LibreOffice makes a “portable” version available that can be installed or run from USB without admin privileges under Windows. It is available from:
