iCloud for Windows not fully initialized.

I just fix the problem just to uncheck this "Internet Protocol Version 6 (TCP/IPv6)" on "Windows 11"

Same things done with me and never found the final guilty actor let’s say. Neither Vpn nor Windows firewall or Java software client etc etc..

I want to tell you more about my own findings and possible work-around. I was initially suspecting that something was preventing the MFA mechanism to work fine because the issue shows up exactly when I am expecting to be offered a notification on my iPhone - notification which doesn’t pop up - about the MFA numeric code which would be needed later on Pc side..to complete the authentication phase let’s say. So, what I tested on my own was to prove to myself that this mechanism MFA on my Windows pc was still working fine and I confirm you it does: If I try to access via pc browser to my iCloud contents I am surely asked to satisfy the MFA step as well, and in fact here on this alternative scenario it works perfectly so the root cause is not on my iPhone settings or into any Pc third party software running. If it was here the root cause, than I won’t succeed to authenticate to iCloud via web browser while in fact I do succeed and I have proved to Apple this evidence. Later on I moved forward to another deeper and Apple-unsupported troubleshooting attempt just to have more elements on my personal experience. I have found the client installation setup file of the software iCloud for Windows version 7.xx - I’ve than of course, first of all, uninstalled the iCloud windows app ver 14.x (you’ll have always two components to uninstall: the main iCloud client and the outlook component) Now, uninstall completed of the 14.x.. So let’s move on with my personal initiative of problem solving: I moved on by attempt of installing the iCloud 7.x and.. guess what… it works as a charm the MFA here!! Yes yes.. it succeed it so you’ll finally have iCloud working again on your pc.. and now you’ll be able to upgrade again to iCloud 14.x installing it by the Microsoft Store and now the MFA stage will work smoothly too as everything else too. Pro and Cons: 1st. please backup all your iCloud data manually BEFORE to do what I described because you never know how downgrading and re-upgrading will behave — 2nd. the old client of iCloud 7.x setup is not made available anymore by Apple on the web.. so.. good luck to find it maybe on some old images of your Windows past years experience.. when the 14.x version was not existent or mandatory to be used. In fact to me the 7.x version developed by Apple was perfect and all the troubles to me started by the introduction of 14.x but that’s my own personal opinion. — 3rd. the very same issue will come up again on using 14.x client exactly after any future Pc BIOS update that you will eventually be offered by your pc manufacturer, why, because after each pc Bios successful update than iCloud 14.x will ask us again to re-do the authentication steps.. and here will restart again the nightmare iCloud 14.x user experience. My conclusion: Bios updates vs iCloud 14.x MFA steps during login into iCloud client stage is the root cause of our issue but no idea on my side on how to get it solved by Apple or Microsoft engineers. Hope with all my heart that they will very soon as now I’m not using iCloud at all on my pc because of the above things. Thank you for reading me till the end.

In the beginning I tried to do this peocedure but didn't work. So then I tried to completely delete this folders:

1. 1. %APPDATA%\Microsoft\Crypto\RSA
   2. %APPDATA%\Microsoft\SystemCertificates

And now iCloud let me do the login without problems.

icloud for windows suceed to work perfectly

my actions

Uninstal icloud

stop & disable all security ,Firewall etc ...

Move laptop to direct ip connections

reload and install icloud for windows

icloud calendar and contacts appear in Outlook

remark : do not change the naming of calendar and contacts newly created

MS photos not yet fully tested

but my Outlook is finally working and synchronising well

thanks for the HELP

On windows 11, resolved the problem by downloading and connecting to itunes app.

After that the icloud app was able to connect to my apple ID. (before that i had the "not fully initialized message")

Let me know if it did the trick for you...

I tried to share a direct link that I found online and Apple wouldn't allow me to post it. So, do a search for "non-microsoft store icloud download" and look for a result in a gaming community in reddit. Someone there has posted a direct link that worked for me.

i installed the older version like some posters recommended. And that actually worked in my case.

I now keep getting nags saying that I should update from my old version. But I haven’t done that now that I’m up and running.

I wonder whether there are others who updated a legacy install like mine? Did the update help or hurt?

Where can you get version 13 of iCloud for windows?

If you go back to page 1 of this thread, dated Jun 14, 2023 3:19 PM, you may find a direct link to iCloud v.7 which I used successfully to fix the problem. Read previous comments for details.

Hi Guys,

I have been using the latest update from a while now and my files and folders are syncing perfectly. I have 2 PC and 1 Laptop. All of them are on Windows 10 Pro. All my files are syncing on all my devices including my iPhone, iPad and all 3 windows machines. Try checking if the app is not being blocked by firewall or your Wi-Fi is set to private and not public. Maybe changing those settings could work. Even try closing all iCloud related processes from task manager and re-start iCloud Drive. That could help.

I tried the above steps, didn't work. Even called Apple and did screenshare with them for a bit.

I too found 13.4.101.0 appx and I'm so happy it's working. It just took me some clever online searching to find it on Reddit.

You can easily find older versions by using your Windows admin terminal and the winget commands. This will dodge 99% of those threat actors and bad files floating around on those websites. Here's the command to use.

Right click your Windows logo, look for Terminal(admin). Once open you'll type in this command; winget search "iCloud" When you find the version you want to install, simply highlight the ID with your mouse, use ctrl + c to copy the full ID name then type winget install <ctrl + v> to paste the ID into the command then hit <enter> type "Y" when prompted by Windows to agree to installing from not their bloated Microsoft Store. Done.

Guys I just tried today and the latest version is working now. I don’t know if Apple has corrected the problem or it was just a luck. I did install vc redistributable setup for 2008, 2010, 2012, 2013 and 2015to2022.

so don’t know what worked but now iCloud for windows is working

Exactly the very same issue, I had it on Windows 10, I've upgraded also to Windows 11, always the very same issue. In fact just after I've entered my credential the login does not move forward to the expected step of the MFA multi factor authentication where on your iPhone should pop up immediately a related notification which allow you to discover the one-time-code to be entered in the pc screen if only iCloud app would move forward as well, but it doesn't.. The MFA by itself is working perfectly on the same PC and environment because in any other scenario where is required, it works smoothly, just like to sing in into this support forum -- I'd really love that Apple could guide us to fix it without expecting us to completely format and re-install our Windows OS. Thank you!

This must be a recent problem, as I noticed it in my laptop (old installation) and it also happened on my brand new PC installation.

The Apple support has not really helped, as they just asked to uninstall/delete various iCloud related files and I stopped this procedure when they asked me to unistall the Outlook. What would be the next step; to uninstall windows or my ERP?

I mainly used iCloud for Windows for the calendar and the solution for me was to move to a new Oulook calendar.

Unfortunately, I have to do some work for this transition, but I can't function without a calendar and at this moment there's no solution from Apple.

PS. I suspect that at some point they will work on this, find the conflict and solve the problem, but I'm sad because it will be too late to go back.
