Shared technology issue

Question

Good afternoon,
I hope someone is able to help me out as the Adobe help team is not. They even withdrew my case while it has not been solved. I wan't to say a few ugly words about that but as that will not help I won't.
Here's the deal:
I owned and used adobe photoshop elements 10.
Thougt I'd move forward by purchasing version 11
Uninstalled 10,
tried to install 11.
Now it's on, Same problem as I think a billion other people are having. Shared technologies refuse.
Logged a case, sent in the log, tried the forum hints still no further.
Making things even worse, I cannot even reinstall 10 at the moment. It also stops.
Log says no problems,
New admistrator account, no help
Disable UAC, no help
Stopped services etc. no help.
Run the installer as admistrator, no joy
I even looked on the cd for the shared technologies, big surprise, they WILL install when started seperately.
is it me or is this just a bad program pretending to be a good one?
PLEASE HELP, I'm without photo processing power now.
If adobe is listening in, my case number was  #0183986706 and has been withdrawn for no apparant reason. Even worse, I work during days, so am unable to try and call the halpdesk during office hours, keeping me in the pickle

Answer 1

Success, Solution found; for future reference I will include the steps supplied by an Adobe helpdesk employee suggested after reopening the case. I add a few comments to somewhat correct the answer to have it work in my environment:
1. create a new admin account Adobe Test; http://helpx.adobe.com/nl/x-productkb/global/create-local-administrator-account-windows.ht ml
          note; the suggested route in the link is probably for a company network environment; just go to the configuration and add a new user with an administration role.
2. Start windows in a changed mode: http://helpx.adobe.com/nl/x-productkb/global/restart-windows-modified-mode-windows.html
3. reboot and start as the new created admin user
4. Copy all files of the CD to C:\ PSE11 Installer\ (the 11 is the version number, should also work for PSE10 etc)
note: additional step; Deinstall all software that starts with ADOBE. i.e. reader / flash / download manager etc.; if this is not done step 5 might not be possible for all directories.
5. rename the following directies bij adding OLD to the name. Note: sometimes an additional approval needs to be granted (just click YES/OK on the question)
     C:\Program Files\Common Files\Adobe               => C:\Program Files\Common Files\Adobe OLD
     C:\Program Files (86x)\Common Files\Adobe       => C:\Program Files (86x)\Common Files\Adobe OLD
     C:\Program Files\Adobe                                     => C:\Program Files\Adobe OLD
     C:\Program Files　(86x)\Adobe                          => C:\Program Files　(86x)\Adobe OLD
6. start the installation from C:\ PSE11 Installer\
     note: from this directory start the AutoPlay.exe
7. Step not mentioned and not yet performed by me: cleanup the C:\ PSE11 Installer\?? Think this should be possible as the installation was succesfull.
8. Step not mentioned but performed, reverse the steps done in step 2 (i.e. msconfig changed services and startup)
Some of the links might be the dutch ones, but I think should also be available in English.
Finaly I can start using PSE11.
Thanks everyone for the suggestions and help
Robert
