You are not able to install Revit (or Revit LT) 2018 due to an Error installing Revit/LT that starts a rollback with ODBC failing to install at he end of Installing Revit 2018 main component. Usually the Icon shows up then disappears a few seconds later when the roll back begins. You can check the log file, and the roll back begins in the log at the ODBCInstallDriver64.
The installation is failing on the attempt to install ODBCInstallDriver64.msi because Windows already has an ODBC driver installed.
A corrected *.msi file (generated by Autodesk) as a work around to the problem, can be downloaded and used to replace the existing Revit (or Revit LT) 2018 install *.msi, on downloaded installers or deployments that include Revit/Revit LT 2018.
