I must say that my problem was solved with reinstalling the Windows 10. It looks there was a corruption in the Windows Installer service that could only have been fixed with reinstall.
1) First I tried if I can install the iCloud with the default Administrator account:
*Click Run as administrator
At the command prompt type: net user administrator /active:yes
Close command prompt, restart, then try signing into the Administrator account.
Try running the file again.
2) Next thing that I tried was:
Press Windows key + R
Navigate to the registry path:
Temporarily modify these 3 registry keys:
CurrentBuild set value to 17134 (instead of 17763)
CurrentBuildNumber set value to 17134 (instead of 17763)
ReleaseId set value to 1803 (instead of 1809)
Install iCloud: iCloudSetup.exe. When finished, do not restart yet. Restore initial values of the 3 keys (step 3). Restart PC and complete setup of iCloud
For Windows 10 in 32-bit version, the path is:
- Also you should check if you have Windows 10 in
S mode installed.
Last thing I have tried before reinstalling the OS was uninstalling all Apple Software this includes iTunes, Apple Support software etc. Please uninstall them in the following order (as stated in this article)
2) Apple Software Update
3) Apple Mobile Device Support
5) Apple Application Support 32-bit
6) Apple Application Support 64-bit
Use Revouninstaller (HOW TO?) to thoroughly remove all Apple Software. Also make sure you uninstall the Apple Software Updater too. Try installing iCloud and iTunes again.
And if you fail after all of this try reinstalling your Windows 10 because that solved my issue with iCloud.
Hopefully this helped for those who have the same issue that I had.
