I am unable to download the Oracle client for version 12c.  I get the following error and an empty file.

C:\Users\\AppData\Local\Temp\verKLtW2.zip.part could not be saved, because the source file could not be read.

Try again later, or contact the server administrator.

Oracle Database 12c Release 2 Client (12.2.0.1.0) for Microsoft Windows (x64)

or

Oracle Database 12c Release 2 Client (12.2.0.1.0) for Microsoft Windows (32-bit)

.  When I try to call the 1800 number my call is dropped.
