Note: McAfee Anti-Virus may have issue with the periods found in the version number of the installer (i.e. 22.214.171.124.) Rename the installer by removing all periods except for the '.exe' and then re-run the executable (e.g. "Toad for Oracle 126.96.36.199 Commercial.exe" to "ToadforOracle9725Commercial.exe".)
Open or view ALL the Permissions or Access Rights on your C: Drive, and make sure the Windows User you are logging in with have Full Read & Write access to that drive. If you are installing Toad in another Drive, do the same with that drive or destination directory in that drive.
