After upgrading to Windows 10, NOD32 wasn't working so I did an uninstall and then when attempting to reinstall, comes up with the following error message: The installer has insufficient privileges to modify this file: C:\ESET\ESET NOD32 Antivirus\callmsi.exe. I did a malware scan and deleted detected items, but still comes up with the same error message. Can anyone suggest how to gett NOD32 up and running again?
