The first and most frequent reason why your iCloud installation could not start is that you have installed several versions of Office on your PC. To solve the problem, you must uninstall all versions and reinstall only the latest version.

First, run the Programs and Functions program to uninstall the applications. (Click on the Start menu, type “Programs and Functions” and press Enter.)
Browse the list of applications and uninstall all Outlook applications you find (right click > Uninstall).
Once you have done this, download the latest version of Outlook and install it on your computer. Alternatively, you can get the version you used before, but make sure you install the latest updates for it.
Now try to re-synchronize with iCloud.

Restoring the iCloud data file

In Outlook, choose File > Account Settings > Account Settings > Account Settings > Account Settings.
Select the Data File > iCloud > Delete tab.
Close Outlook
Open the iCloud application (select Windows > Control Panel > iCloud).
Select Configure contacts, calendar and iCloud tasks in Outlook.
Once the installation is complete, open Outlook.

You may be asked to enter your iCloud password, depending on whether you have already registered it or not.

  1. Click on Start and start typing “cmd” on your keyboard.
  2. Cmd should appear with a black icon in your search results.
  3. Right-click on it and select Run as administrator.
