Computer.Dell Precision M6300, Intel Core 2 extreme, with Windows Vista Ultimate.
After experiencing a BLACK schreen, where only the cursor was visible, and active, I received the instructions shown in the attachment.
This ALMOST returned my computer to its original working capacity.
However, I cannot open Microsoft Office, iTunes, QuickTime player, Open Office, Google Earth any more. When I try I get a message saying: This action is only valid for products that are currently installed. Or: This update package could not be opened. Verify...........and verify that this is a valid Windows Installer update package. Or: A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.
Other programs, like the ones mentioned below, work fine.
A rendering program, Artlantis Render 2, could work, if Quicktime could be opened, as it uses some QT properties.
I have tried to un-install and re-install Quicktime, without success.
Can anyone out there help me re-connect these broken links. I have a feeling that the tampering with regedit may have caused the problems.
