Welcome to the forum.
I am not familiar with that particular error message, but this is a general, Adobe installation checklist: http://forums.adobe.com/message/3419692#3419692
I would start with it, to see if there is something you are doing, like leaving anti-virus software run, while attempting to install, that could be causing the error.
I had a similar error. My work around was to start the organizer (Photoshop Elements) first. If that works for you, great. YMMV
I am not familiar with that error message either. You originally posted on November 30, 2013. It is now December 8, 2013. Has your issue been resolved yet? If not, then I would offer the following troubleshooting scheme based on what you have written.
1. Open a project. Go to Help Menu/Deactivate and Deactivate. Close out of there.
2. Uninstall Premiere Elements 9 via the usual Control Panel Route.
3. Run the computer through the ccleaner (regular cleaner and registry cleaning parts).
4. Reinstall Premiere Elements 9 with antivirus and firewalls off.
5. Reinstall the Premiere Elements 9.0.1 Update.
Is the problem resolved.
We may have to look deeper into your original reasons for troubleshooting the program
i tried to reinstall my copy of Adobe Premiere Elements 9.0 because of problems with creating/loading any projects.
We may need to distinguish between damaged projects versus a program that has become non functional.
Please review and do not hesitate to ask for clarification on anything written.
Add On...If there is any indications of a problem with Premiere Elements 9.0/9.0.1 Elements Organizer 9 we can look into deleting its settings file and/or creating a new catalog. But, I do not see any indications for this at this time.
You might find this Adobe document on damaged projects of interest.
What is the relationship of your experience to Premiere Elements? Where you only dealing with Photoshop Elements and its Elements Organizer? Or, where you dealing with the Elements Organizer of Premiere Elements? In your case, what versions of the programs were involved?
I am trying to determine if your fix applies to
a. opening the Photoshop Elements Elements Organizer first to get rid of this error message, then opening the Photoshop Elements Editor
b. opening the Premiere Elements Elements Organizer first to get rid of this error message before working in the Premiere Elements Editor workspace.
Thanks in advance for the clarification.
