Hello Steve,

Thank you for your reply.
It was stupid of me. My fresh install of Windows XP SP3, as I wrote, was done without all Windows updates and that is asking for troubles.
I have deinstalled PRE9 first and then I made a connection to internet to download and install the Windows updates (> 107 updates).
I reinstalled PRE9 and not that error message anymore.
By the way in both cases (without and with Windows updates) the last message window
of the PRE Install Wizard (printed below between the ======= lines) was that PRE9 was installed succesfully!

You wrote that QuickTime is required for PRE9. If I read again the last message of the Install Wizard I conclude that QT is
only necessary if you use to play MOV, MPEG4 or 3GP video.
But as long as you do not use that, PRE9 should run correctly.

====================================================================== ===========================================
Install wizard completed.

The install wizard has succesfully installed Adobe Premiere Elements 9. Click Finish to exit the wizard.

Notes:-

1. Adobe Premiere Elements requires QuikTime be installed on your PC in order to play MOV, MPEG4 or 3GP video.
After installing Premiere Elements, you should install the latest version of QuickTime.
====================================================================== ============================================

So this minor problem is solved, but still not my major problem during the use of PRE. It is that PRE9 must quit as soon
it comes in conflict with module atioglxx.dll after starting a NEW Project (File-New-Project or Ctrl+N) or OPENing a project.
All pc hw drivers are up to date, done a memory test,  pc meets the min. requirements as stated by Adobe etc.
I have tried to log with SysInternals Process Monitor to find the cause and analyzed the DrWatson log too.

I like to find a debuggerspecialist because
the failure in the Dr.Watson log points to a line of assembler in function atioglxx.dll!atiQDS

Hello Steve,

Thank you for your advices.

The earlier mentioned error message: " The Windows Installer Service cannot update the system file C:\Windows\system32\msxml6r.dll because the file is protected by Windows. You may need to update your operating system for this program to work correctly" came again after a re-install of PE9 after a restore of a fresh installed Windows (incl. the updates now). Probably this could be an explanation below:
When installing PE9 on a non-English Operating Systems (I have the Dutch version) the installer attempts to replace the file msxml6r.dll with the English version of the same file. Since XP SP3, this file is already present on the system and is protected by the OS. This generates probably the error. That is, I think, also the reason that you do not get this Error message on your system.
It should have no consequence for the installation of PE9 on my "Dutch" system.

I have taken over the following actions from your advices to see if it helps to solve my major issue (PE9 hangs due to atioglxx.dll http://forums.adobe.com/message/3609712#36097121).

1. Installing QuickTime afterwards.
2. Having used Advanced System Care to clean.
3. I have again registered PE9 with my Adobe ID.
4. By accident I saw a newer version ATI driver and installed it.
5. Removed BadDrivers.txt
It is a pity that all those actions did not solve the major issue.

If you have more tips or how to trace where it is going wrong, they are very welcome.

I have used Process Monitor and Windbg without succes so far

From Windbg I can startup the PE9 Welcome screen by opening Adobe Premiere Elements 9.exe, but as soon as I have chosen to start a new project then PE9 is exited and Adobe Premiere Elements.exe should start but I can not manage that within Windbg.
