Alan,

Usually no problem adding newer version on top of older versions. However with 
the introduction of JAWS 10 they changed the video intercept strategy from 
Video Chain Manager (VCM) to Display Chaining Manager (DCM) and I had no end of 
serious problems when I tried to install JAWS 9 after JAWS 10.

Since you've already installed JAWS 11 you are using the DCM and your JAWS 9 
may not work properly when installed after JAWS 11 (VCM after DCM).

I would recommend that if you really want JAWS 9, then do the following:

1. Set a restore point.
2. Back up the enu folder in both the user and shared folders.
3. Completely remove JAWS 11 including shared components.
4. Install JAWS 9
5. Reboot and make sure it works.
6. Install JAWS 11.

If something goes wrong, you may need to have FS help over the phone to clean 
out your registry while you use Narrator for speech, or have sighted help. It 
was a nasty process for me.

Or just don't bother with JAWS 9 now.

  Dear Dave,
  Strange you bring this up.
    After my Windows Operating System crash, and a "reinstall" which wiped my 
main "Systems Drive" clean, I reinstalled JAWS 11, latest updated, but now I 
found my JAWS 9 disk, and I also want 2 JAWS versions on my computer, as I have 
always had going way back to JAWS 3.3.

    Any problem with reinstalling an older version of JAWS when you have a more 
current one already installed?

    I bet you might think this a silly question, well you will get a lot of 
those from me, sorry!

    Zdenek,

    If you haven't already done so, I would leave JAWS 11 installed. I never 
remove a previous version until I have two versions higher installed, and both 
working very well. I always allow myself to run the older version if there 
should be some unwanted "feature" or bug in the new version.

    For example, I still have both JAWS 9 and JAWS 11 on this machine with JAWS 
12 and am currently back to using JAWS 11 until FS fixes some problems with 
Outlook 2007 calendar.

    Just my suggestion.

      Hello lissters:
      I purchased my jaws 12 and I would like to uninstaal my previous versions 
of jaws jaws 10 and 11. When I started the uninstalation process I got the 
choices to uninstal jaws only or uninstal jaws and shared components. Which one 
shall I choose?
      Many thanks.
      Zdenek
