Upgrade to EV80SP2 from EV7.5 - cannot write to InstallSXSRuntimes.log

When you get this error, verify the Environment variables.

I had this, and it turned out the the TEMP variable pointed to c:\temp, instead of to %userprofile\localsettings\temp

After I changed this, logged off, then on again, setup ran through.

Just a note...
