Error 1303. The installer has insufficient privileges to access this directory C:\Program Files\LibreOffice\program. The installation cannot continue. Logon as administrator or contact your system administrator.
Upon attempted ver. 6.2.4.2 installation (Windows 8.1), an error message says that I should login as Administrator, which I already have. All User Groups have Full Control. There is no option to Run as Administrator. How may I overcome this obstacle?
