Unrecoverable Error during Install

Right at the beginning of me trying to install TOAD-SQL Server, I get the following error:

"This package installation failed because the MSI installer internal unknown error."

I have downloaded the MSI several times, but I always get this error.

All hard/software requirements are met and validated by the installer and myself manually based on documentation.

I am lost as to the error.

Error in log file is (partial) :
