    Multiple versions of Java

    I just ran Secunia's on line Security Inspector. It reported that I had several versions of Sun Java JRE, only one of which, 1.6.x/6.x was up to date. It also reported similar findings for Adobe Flash Player. It appears that these programs don't uninstall earlier versions when they install an update. Should I go to Add/Remove programs and uninstall all but the latest version?
    Also, did Macromedia Flash Player morph into Adobe Flash Player? If so, can I remove the Macromedia ones?

    Re: Multiple versions of Java

    I alway uninstall previous versions (and yes, MacroMedia Flash is now Adobe Flash) and I have never experienced problems, but there are some applications that require a specific version of Java Runtime Edition.
    So I'd make a restore point before uninstalling the older versions, so that you can go back if an application doesn't work any more.

    Not wishing to doubt your breathtaking expertise, but is Java considered as part of the operating system to be covered by the System Restore Point process?

    Re: Multiple versions of Java

    I have to admit that I've never yet had to use System Restore, so I don't know whether it covers Java.

    Re: Multiple versions of Java

    I agree with Hans about uninstalling previous versions of Flash; whether it is simply done by using Add or Remove in CP or, perhaps better, the Adobe Flash uninstaller. The latter has been mentioned some times in the Lounge, and I have been using it for several years. I just make it a habit to download the latest uninstaller.

    For a little more info, see my addition to Tony's post in the second half of this <post:=741,517>post 741,517</post:>.

    I do not use Java Runtime Environment (JRE), it may be as Hans says, and that some application may depend on a specific version, but that should be easy to check.

    As to System Restore (SR):
    I would say that a simple rule (that I just made up <img src=/S/grin.gif border=0 alt=grin width=15 height=15>) is: that if it comes with an installer and it has been installed after the Restore Point you are going to use, then uninstall it before using SR. If you want to keep a program, reinstall it after the systems restore operation.

    The tricky part, perhaps, would be to remember the installed programs that didnít create a RP when you installed them, and one forgot or skipped to create one, since they, obviously donít show up in SR.

    One could perhaps create a RP before uninstalling something (but it isn't the purpose of SR), but if one wants the program back, in the vast majority of the cases, simply restoring with SR will not restore all files and settings.

    Re: Multiple versions of Java

    Thanks for the info. I will download the Adobe Flash Uninstaller, then close down for the long weekend. I assume I can uninstall the Macromedia Flash player,since it has been superseded by Adobe. Next Monday I'll deal with Java.

    Re: Multiple versions of Java

    My own <img src=/S/2cents.gif border=0 alt=2cents width=15 height=15>: I have tried System Restore many times, and every single time it has failed and proven itself completely useless. So I do not think it is a good idea to rely on it.

    Microsoft says in its consumer friendly article -- "Use System Restore to Undo Changes if Problems Occur" -- that it can reverse "system changes" but that's rather ambiguous. A page on MSDN says a bit more:
    <hr>System Restore monitors a core set of system and application files, archiving the states of these files before system changes are made. System Restore also saves a full snapshot of the registry and some dynamic system files. When System Restore detects that the user is not actively using the computer, it compresses the registry and any file copies made.

    System Restore requires a minimum of 200 MB of free disk space on the system drive at installation. When the amount of free disk space falls below 50 MB on any drive, System Restore switches to standby mode and stops creating restore points. All restore points are deleted at that time. System Restore reactivates and resumes creating restore points as soon as 200 MB of disk space is free on the system drive.

    The files that are monitored or excluded from monitoring are specified in the file %windir%system32restoreFilelist.xml.<hr>
    I glanced at that .xml file, but did not find it immediately helpful in understanding whether a newly added DLL file, for example, would be removed in a system restore operation, if there was no earlier version to restore.

    Re: Multiple versions of Java

    There are, no surprise <img src=/S/smile.gif border=0 alt=smile width=15 height=15>, some do's and don'ts with SR, as with all programs, that one should take the time to learn before using the program. The biggest and most frequent reason to support questions for any application is that the user has assumed that the application does one thing, when it in fact is designed to do something else, when you use it in a certain way. (It may be Office, Windows whatever etc.; programs as a whole, or just a certain setting).

    But people in general do not take the time to do a little reading. And especially good would it be to take a closer look at what comes with the new OS one just got.

    How many test that the Safe Mode is working, that they can boot from the install media and use the Recovery Console etc. etc. BEFORE they need it? Not many I guess.

    It is a System Restore application (and I agree that's a bit vague name, but what would have been better? <img src=/S/laugh.gif border=0 alt=laugh width=15 height=15>), and is just one of several layers in the OS as you know; how many common users use or know about the roll back driver feature in Device Manager etc. etc., I'd guess they'll go for Add or Remove in CP and uninstall those drivers.

    SR is designed to take care of glitches and problems in the OS. That people add or remove programs every day wasn't directly part of the equation. <img src=/S/grin.gif border=0 alt=grin width=15 height=15> That is something one has to deal with later on. Thus simply uninstall before using SR. But some fail that and makes a worse mess of what was once an easier problem.

    That said, I don't take SR lightly; it depends on the situation, but it is not the first thing to try, and not the last one.

    A list of file extensions that SR monitors (on the monitored drives; one has to remember what areas it covers also).

    A DLL file would be removed, if it was on a monitored partition and if there was no earlier version to restore.
