I was not able to run ASDM 6.4(9) through Java Web Start. On the Win7 x64 computer, I already installed JRE 8U25 x64 and found not working. So I uninstalled that version and installed an older version JRE 7U40 x64 and still not working.
Basically for both version of Java, when I tried to run ASDM as a Java Web Application, it gave me the message:
Java Web Start is required to run ASDM, but it is not installed on this computer.
What did I miss? Can you help?
