ASDM - java runtime environment is not installed

Hi All,

I have an ASA runing asdm 6.3(3). I can launch the console from the web page but can't install it. Here is my config:

ASA 6.3(3)

Windows 7 x32bits

Java 6.0.21

ehrn I try to install it I get the following


any ideas?

Many Thanks!



Working with a company not wanting to progress and ran across this same issue and uninstalling the latest v. of JRE (currently 9 something) and then going to the link I've provided below to install the archived version of JRE 6u7 586 worked as stated...


Saw this thread while was searching for this solution. While was monitoring after a working workstation with some ancient 1.5 Java I discovered that all you need is:

  1. Access your ASA via https://-ip-address-or-name-/admin/public/asdm.jnlp and save the file
  2. double-click it in Windows which will open Java and ASDM.

This works with all the latest JREs, I'm using 1.7.latest.




Yep that works but when I go to my ASDM app still not working. How to fix that? =)


Found the answer to my question and maybe all above.

I was using java 7.5. Mistake. Deinstall it and install latest 6 version of java which as of today is 6.33 from let's say here

Everything works after that.



Hello Joro,


I have worked on a lot of issues related to this java version and ASDM/IDM.

Glad to know that you have resolved it, Some kudos for you

BIG THX U SO HELP!!!!!!!!!!!!! <3   cisco not help me


this post to use https://-ip-address-or-name-/admin/public/asdm.jnlp was very useful

New Windows 10   Java 8u72  both 32 and 64  ( no jre 6 involved )

Control Panel ->  Java ( yes 8 ) -> add above link to security tab exception

Then just use the links  ( I used I.E 11 ( not Microsoft "edge" ) just because)

Even with the java exception defined you have to tell java "Security Warning" pop up "Continue" every time - no "always trust"

Allow caching of software from each device->

In my case:

    2 devices = "Cisco ASDM-IDM Launcher v1.5(46)" - ASDM 6.2F for FWSM

    1 device = "Cisco ASDM-IDM Launcher v1.5(49)" - ASDM 6.3 for FWSM

If you have different versions of ASDM sent from the devices you may get errors popping back and forth in the upper left device list.. I just created different "IE Favorties" and start over for each device of different version software. That seems to let the "session" have the correct cached software - (actually you can pop to different devices if they are running same versions)

I thought I would have to play games with finding old JRE6 32bit ( load it in addition to the latest JAVA ( 8 )) and create .bat files setting JAVA_HOME then execute ASDM-IDM Launcher --- etc .... but I did not


worked flawlessy, thank you

i had the same problem

and solution i found after long time was

1) for win 7 64bit install 64bit java run time 6.0

2)for win 7 32bit install x586 java run time 6.0

older version of java are in archived in java you have to log in to download older version

it works fine with the asdm version i had


and just to make it more blurry and confusing:

I am running windows 7 x64 and have of course also had weird problems with java - but - as far as I can see it mostly come from either missing permissions or corrutped downloads etc. I am running Java ver 7 update 17 and ASDM/IDM launcher 1.5(56) and has no problems with launching the ASDM directly from that (ver. 7.1(1)52) - 32 bit java runtime

I have also a Windows 2003 x86 with Java ver 7 update 9 and running ASDM/IDM lancher 1.5(56) and running ASDM ver 7.1(1)52 there also - without problems. When you suffer under these java problems I would suggest first to try to clean-up older sw packets - these jar applets which is stored somewhere (from the java controla-panel you can delete these) and after that de-install your Java RTS - and then re-install the newest. You are probably fighting with some old in-compatible modules...


Well I have to agree. Someone fixed the stuff and it works fine now.

Windows 7 + java 7 Update 17 + asdm 7.0 works just fine.


I did have my ASDM working with several firewalls with various software versions but my PC crashed and ever since I am having problems with ASDM.

My PC is Win 7 x32bit

I can get ASDM to launch using 6.3(3) which is on a firewall that I had downgraded but if I try to use any of the up to date firewalls that are running 7.1(1)52 then I get an error.

If I try the ADSM-IDM launcher v1.5(56) then I get a no disk space error on the PC when there is clearly enough disk space and if I try to just run ASDM from the browser then it looks as though it will run but just doesnt load.

I am using an older version of Java ver 6 update 26

Should I try another newer version of Java?


Windows Server 2012 R2 X64 - I downloaded and installed 32-bit Java jdk-6u45-windows-i586.exe which is the last version of JRE 1.6 and it worked.  Java 1.7 does not work.

Please uninstall your Java run time environment and reinstall it and then try.


hi bro.. after having big headache for 3days with this error, i've found the solution.

>uninstall existing version of java


>install java jre version "6"  (yes version 6 not the updated)

>set path and system path


now install asdm!!



the asdm java version should be compatible with the pc's java version
