ASA version 8.0(4)
ASDM version 6.2(5)53
OS: windows 2008 R2
Use Google Chrome access ASA5510, download ASDM-IDM package. Filename is dm-launcher.exe.
Double click got following error message.
Error Message shows Java Runtime Environment is not installed on this machine.
Actually when using browser to open http://www.java.com/en/download/testjava.jsp page, Java info on this computer has shown up. It is running on SE 7 U9.
After did lots of google research, found one perfect solution here. Deinstall version 7 and install latest 6 version of java from http://www.filehippo.com/download_jre_32/12538/
That works for me.
