The for this file is Oracle’s official archive. Oracle maintains a historical archive of all old JDK versions, but you will need an Oracle account (free to create) to access it.
Before downloading, verify that your project truly cannot be updated to a modern, supported JDK. If the answer is "no," then proceed with caution—download only from the official Oracle archive, install in a controlled environment, and treat this old JDK with the respect (and isolation) that a historical artifact requires. jdk-7u67-windows-x64.exe free download
