Apple iCloud.exe is the executable file associated with the iCloud app. If this file doesn’t open, users would not be able to use the iCloud service and other associated apps.
The causes include the Apple software not being up to date, missing Media Feature pack, anti-virus software blocking the program, inability of the file to connect to the server.
Try disabling the anti-virus, Windows Defender, Windows Firewall temporarily and check if it helps.
Thereafter, proceed with the following troubleshooting steps:
Solution 1] Make sure Windows Media Features is present in the system
1] Some Windows systems come without Windows Media player and in other cases, the Media feature Pack is disabled.
2] In case the Media Features pack is disabled, press Win + R to open the Run window and type the command appwiz.cpl.
3] Press Enter to open the Programs and Features page.
4] Click and open Turn Windows features ON or OFF.
5] Navigate to Media Features and check that option.
6] Click on OK to save the settings and restart the system.
Solution 2] Update the Apple software
1] The Apple Software Update program is installed in Windows systems as a part of the package along with iCloud or iTunes.
2] Search for the Apple Update Software in the Windows search bar and run it to update the package.
Solution 3] Check if you are able to connect to Apple’s server
1] Try opening apple.com. If it works, everything’s good.
2] If apple.com does not open, try pinging it through command prompt.
3] Search for Command Prompt in the Windows search bar and open it.
4] Type the command ping apple.com and press Enter.
5] If you do not get all 4 replies, contact your network administrator for help.
6] You could also disable proxies set in the system and use the network troubleshooter (Settings >> Updates and Security >> Troubleshoot >> Network Adapter troubleshooter).
Solution 4] Reinstall the package
If the above solutions fail, you might consider reinstalling the iCloud/iTunes package.
