Hi

I think  you need to do a manually remove of all traces from your previous Acrobat version. Don't use a registry cleaner, they generally are too crude and do more harm then good if things go wrong.

As you have installed 8 Reader over the 7 Pro install you need to remove this too:

Reboot and log in as administrator account. Install Acrobat.

Do one of more of the following solutions:
Solution 1: Use the Microsoft Windows Installer CleanUp Utility to remove corrupted registry entries.

Warning: The Microsoft Windows Installer CleanUp Utility only removes registry entries created by the application installer. Files and other registry entries for the application are not removed by this utility and could cause inadvertent effects on the system if not removed. If you use this utility, you may have to reinstall other programs that use MSI (Microsoft Installer). Caution is advised. Read information about the utility on the Microsoft website at http://support.microsoft.com/default.aspx?scid=kb;en-us;290301.

   1. Download and install the Windows Installer CleanUp Utility.
         1. Visit the Microsoft website at http://support.microsoft.com and and search for msicuu2.exe.
         2. Select the article "You receive the 'This patch package could not be opened' error message in an Office program."
         3. Click the link for the msicuu2.exe utility under Resolution Step 1.
         4. Save the utility to your desktop.
         5. Double-click the msicuu2.exe file and follow the on-screen instructions.
   2. Identify the version of Acrobat or Reader that is causing the issue and correctly remove it from the system using the following steps.

Note: Acrobat or Adobe Reader will attempt to remove earlier versions of Acrobat or Adobe Reader if they reside on the machine. When the removal cannot complete, an error message is typically displayed. In this case, you should attempt to remove the earlier version of Acrobat or Reader using Add/Remove Programs in order to determine if the earlier version is the source of the error. Proceed to Solution 2 to resolve this issue.

If the error is generated by Acrobat or Reader 6.x or 7.x, then do the following:

   1. Remove all updates that do not generate an error message.
   2. Choose Start > Program > Windows Install Clean Up to start the Windows Install Clean Up utility.
   3. Select the current version of Acrobat and choose Remove.
   4. Reinstall the current version of Acrobat.
   5. Apply all updates.

If the error is generated when an earlier version of Acrobat or Adobe Reader prevents the installation of the current version of Acrobat or Adobe Reader, then do the following:

Important : These steps require the installation media and serial number for both versions of Acrobat. It is important to remove the previous version with the Windows Installer Clean Up Utility and then reinstall that application and correctly remove it from your system. This process removes all extra information from the operating system that may be left by the Windows Installer CleanUp Utility.

   1. Remove all updates that do not generate an error message.
   2. Choose Start > Program > Windows Installer CleanUp to start the Windows Installer CleanUp Utility.
   3. Select the previous version of the application and choose Remove.
   4. Reinstall the previous version of the application.
   5. Remove the previous version of Acrobat or Reader using Add/Remove Programs, and then restart your computer.
   6. Install the current version of Acrobat or Reader.
   7.
      Apply all updates.

Solution 2: Remove the Acrobat or Reader Windows Installer registry key.

Disclaimer: The Windows registry contains information critical to your computer and applications. Adobe does not provide support for problems that arise from improper modification of the registry. Adobe recommends you have experience editing system files before you modify the registry. Make sure to back up the registry before modifying it. For more information on the Windows Registry Editor, refer to your Windows User Guide or contact Microsoft Technical Support.

Important: Verify that the correct registry key is selected. When viewing a path of HKEY_CLASSES_ROOT\Installer\Features\68AB67CA3301004F7869010000000020, only the 68AB67CA3301004F7869010000000020 key should be selected. If the name does not match exactly, do not select the item.

   1. Choose Start > Run.
   2. In the Open box, type regedit and then click OK.
   3. In the Registry Editor, select the appropriate Acrobat registry key:
