The thread title states the problem. I have downloaded JDKs several times, most recently a half-hour ago. When I double-click on them, Windows prompts me to confirm that I want to install the software. When I clear the prompt ("OK"), the prompt goes away, but nothing else happens. The same situation exists when I confirm that I would like to accept the most recent Java update.
My machine is an AMD Phenom II Black dual-core
8 GB RAM
17 TB HDD
Windows 7 Professional 64-bit
Why can't I install a Java compiler on my Windows 7 computer?
