Verify that the specified log file location exists and is writable”. There are high chances of coming across this error when the Installer logging feature in Windows has been turned on, but due to some issues, the log file is not written properly by the Installer service.

Other causes are missing installation files, or corrupt Windows Installer, or the bad state of Windows Explorer.
