Re the Prebuilt Developer VMs at http://www.oracle.com/technetwork/community/developer-vm/index.html , the "Database App Development VM"
I am trying to import the Oracle 12c Oracle Technology Network Developer Day - Hands-on Database Application Development lab into Oracle VM Virtual Box 4.3.10 on Windows 7 64bit. I get the error "Could not create the clone medium ..<path>... (VERR_VD_VMDK_INVALID_FORMAT) with Details showing Result Code "VBOX_E_FILE_ERROR (0x80BB0004)" for the Component "Appliance".
I have repeatedly attempted a downlad and import and failed. Although the file size (5,215,947,264 bytes) matches, the md5sum doesn't seem to match.
Has anyone else seen issues with this appliance ?
