At work, we are using Kronos for timekeeping purposes. The previous version we used was Java JRE 1.3.1_02 and upgraded to JRE 1.4.2_06. We did this via CA's SDO system. After all upgraded, we upgraded the server to the higher version.

Question is, without creating an uninstall package for 1.3.1_02, can we disable this version via registry hacks? Anyone know the hacks? Tried to write an uninstall package and messed everything up. We need to disable the lower version due to security issues.

You may also write me direct at : ben.grossi@town-sports.com. Thanks

Just delete the java files and then there are no more vulnerabililties. Don't bother messing with the registry. It should only access the latest version, if that is the only one there.

I understand that, but we have 1900+ users, between DC and Boston. Removing 1.3.1 on the test environment messed up the higher version. Just looking for the registry key to disable 1.3.1_02.

To determine the version of your JDK software, use the following command at the Start --> Run --> "cmd" --> OK:

java -version

This will tell you which version is actually running.

My guess is that the old version is still in the way somehow.

See Here:

Now, I have never used Computer Associates products to do network installs or uninstalls. I think what you need to do at this point is uninstall all Java's on all of your systems and reinstall the JRE that you need.

Does CA's SDO support using the Add/Remove programs feature in Windows?

Do you pay for support from CA SDO? or Kronos?

Either of them may have automated methods of doing this.

Here is how to remove MS JVM from your systems.

I think you answer lies in this post at Sun's forums.

OK, I found a nice document on Sun's site that describes how to install/uninstall silently on windows. Unfortunately, your old version not only interferes somehow with the new version, but it does not support a silent uninstall. This is too bad.

You will need to create an uninstall for this older version.

If I were doing it I would reimage a test system, and then remove the MS JVM. See my eariler post.

Then I would go through the registry and try to find all of the entries that relate to java. I would then remove them, make a copy of the registry, and test.

This Brute force method is time consuming though.
Most of the Keys are in HKLM/SOFTWARE/JAVASOFT/Java Runtime Environment/1.3.xxxx

I think you should try searching Sun's documentation. You know best what you are looking for, and the support and documentation is pretty extensive.
