I can't open Microsoft Outlook anymore after I installed CDS. Why?

After I installed Copernic Desktop Search, I can't open Microsoft Outlook anymore.

By clearing and regenerating the Navigation Pane for the current profile of your Microsoft Outlook, you should be able to run it again.

Open the Run window in your Microsoft Windows start menu (All Programs > Accessories > Run).

1. Type outlook.exe /resetnavpane
2. Click Ok.

If that method does not work, please try this :

Open the Run window in your Microsoft Windows start menu (All Programs > Accessories > Run).

1. Type regedit
2. Locate : [HKEY_CURRENT_USE]SoftwareMicrosoftWindowsNTCurrentVersionWindows Messaging Subsystem
3. Delete the Profiles key under the Windows Messaging Subsystem key
