You need to do a "clean" install:
1. Uninstall Reader using the Control Panel (Programs and Features - Uninstall a Program).
2. Download and install the Windows Installer Cleanup Utility (msicuu2.exe - "google" it).
3. Run the Installer Cleanup and remove ALL Adobe Reader installer files (9 and any previous versions).
4. Reboot your system.
5. Download and reinstall Reader 9.
Thanks for your reply. I have tried doing this. But now realise it's because I tried to uninstall Adobe Creative Master Suite CS3. It hasn't uninstalled completely and has left traces of it still being on my system. It shows up in my programmes, but will not uninstall and I am at a loss now, as to what to do next. Obviously it is still trying to install, hence the message boxes saying it's installing, then error codes showing up, but it isn't complete. Any ideas? Many thanks.

You could always "wipe the slate" clean.
Any and all Adobe folders would be manually deleted. (Shift+Delete to remove them from the hard drive, not send to the recycle bin)
Click Start and Run. Type regedit and hit enter.
Under HKEY_LOCAL_MACHINE\SOFTWARE delete all Adobe Folders (not just the keys, the whole folders - click once and hit Delete)
Under HKEY_CURRENT_USER\SOFTWARE do the same
Under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon Change the value for the AllocateCDRoms entry to 0. (Right click and select Modify - type 0 and hit enter)
Exit the Registry Editor.
You should not see this error anymore
Note: I only recommend this because you indicate that you have already attempted removing the entire creative suite. This will render it unfunctional if you do it. If you aren't comfortable with editing your registry, disregard these steps.
Hi...thank you for this.
I have just used the Adobe cleaner for WinCS3, combined with the Windows Installer Cleaner. I did it to level two and it seems to have uninstalled the whole of CS3 and Acrobat 8. If the problem recurs I will try it to level 4, as used on another forum. I am now keeping my fingers crossed. I thought my PC had had it, as it was effecting everything. Many thanks for your help.
