iCloud for Windows not fully initialized.

Same here. Windows 10 Home. Have tried numerous solutions... disabling anti-virus and firewall, etc., etc. Stopping all but MS services using msconfig. Uninstalling, reinstalling - many times.

The proliferation of "Me too's" on this page certainly suggests that something has been changed, either by Microsloth, or Apple, in recent times.

Just get this every time:

Interestingly, iCloud installed with no problem on an HP Elitebook running Windows 10 Pro.

Still investigating: will post a solution if we can find one!

Cheers

It works! Hallelujiaa!! Thank you so much RB000 and Jatinder and everyone :-)

Let me also tell you that after installing the version 13, I've authenticated without even been asked for the MFA step, so, instead of restarting the pc as I was asked to do by an error message from iCloud,

I've chosen to immediately upgrade to 14.x from the Microsoft Store and than restart my Windows PC. So it works smoothly without asking me to perform MFA to get me in.. Let's see in the future, post next Bios update how it will behave

Kind regards

Updated to current Windows 10 Home updates. No change to iCloud problem.

Interestingly, the MS install/uninstall troubleshooter doesn't even detect that iCloud has been installed. See here for the troubleshooter: https://support.microsoft.com/en-us/topic/fix-problems-that-block-programs-from-being-installed-or-removed-cca7d1b6-65a9-3d98-426b-e9f927e1eb4d

So the MS Store version of iCloud is not fully installing for some reason.

Helpful post, delavega79! Thanks for that. So the conclusion is that transition to the new (14.x) version of iCloud from the MS App Store has created a conflict with something in our W10 Home/?Pro operating system. Yesterday, Apple's Andrew ran through a long list of possible conflicting items, which he had been provided by their engineering team (eg. Acronis, Malwarebytes, etc. etc.), and we tested each one without discovering the guilty party. I also submitted about 100MB of diagnostic data (msinfo32.exe dump, iCloud tracking, screenshots) from my system for examination by Apple engineers, so maybe we're moving closer to identifying the exact problem. (BTW, running DISM and SFC.exe on my W10 system did not detect any corrupted files.)

That is very helpful, delavega79. Thank you taking the time to share your experience.

Of course, you can't even log into this Discussion page without MFA working! But you seem to have identified one half of the incompatibility issue -- the introduction of iCloud for Windows v.14. The burning question is: what is v.14 incompatible with on some PCs running Windows 10 and 11?

Yes yes thank you I’m fully aware about related risks on using certain standalone installation packages. I fully agree on your heads-up. Let me say that if you are an Acronis user as I guess you are, perhaps you better have on your old pc Windows images the official Apple iCloud installation client 7.x which was, at those times, made available by Apple site or deployable directly by Apple Updates Tool

Dear R8000 and WPeterG I'm immensely grateful for this solution that you can't even imagine how much! In the past when I've engaged Apple support via phone (I am entitled for Apple Care+ by the way) the Tier2 engineer which was troubleshooting with me, as the first level support agent super kind was not iCloud-skilled, was almost making me feeling guilty of not being a Mac-User simply because, according to his feedback to me, it was clear that the issue was caused by Windows10 limitations and because I was keeping myself into W10 instead of migrating to the newest W11 OS, at least... I was explaining to him that W10 OS has to be considered fully supported till at least 2024 according to my knowledge but... no changes into his mindset. - For more when we discovered that by creating a new user even in W10 it was visible that iCloud 14 was working fine, he mentioned to me that If I was a Mac user I would have had easy experience in switching everything (sw, configuration, settings, etc..) from UserProfile XY to newUserProfile XY, while in Windows he had no glue and no idea on how to do it easily -- so -- in the end, I've never implemented fully what he was pushing me to do.

Those time after such experience I was posting a polite but detailed resume of my issue and experience had with the above story but my post has been the same day removed by moderator because in my message I was including the link from where - by myself - I have been able to source the iCloud 7.x client installation package. Such internet link was probably braking the Apple Forum Support policy, my mistake, but they could have been keeping at least my thread and message which took to me hours to be composed politely and accurately detailed... but.. eh.. no... zero... nada :)

When I saw here the latest post by R8000 I've immediately jumped to the link and tested the proposed plan of actions because I was afraid that could have happened the same destiny also to such message

Guys, when I installed the iCloud 13.x version, I've briefly noticed that, during the deployment, it seems to me it add some useful C++ or java libraries (I can't recall now) and I believe that this minor step is the success key which makes iCloud 13.x successful to complete and open up properly later on. Last thing to add here, is that the very first time that I've run iCloud 13.x post installing it, I was again expecting to be offered and asked the OTP due to the MFA security logic behind.. but surprisingly no, I've never been asked for it. Neither later, when I've on my choice decided to upgrade immediately to iCloud 14.x and restart the pc as required.

Wish you all the best guys and hope that Apple will sort out soon and completely the issue with iCloud 14.x native package offered by Microsoft Store hub

Warm regards, Diego

If ever there is a fix that an ordinary person can follow maybe someone can private message me. No idea what people are talking about. Only know that mine doesn't work and I keep getting the message.

Dear Fellow Computer User,

I feel your pain... As far as I can tell, the version of iCloud that you download from the Microsoft App Store doesn't work as it is supposed to. My opinion -- and it's only an opinion at this stage -- is that the MS Store version fails to deal correctly with previously-installed version/s of iCloud. (I suspect this because I had no problem installing it on a laptop running Windows 10 Pro, which had not previously had iCloud on it.) The problem on my Windows 10 Home PC showed up at the two-factor authentication stage, where the installer sends a text message to your phone with a six-figure code. The process just stopped at that point.

I tried uninstalling/deleting everything Apple that I could find on my PC, but to no avail: the MS Store version of iCloud still wouldn't do the two-factor authentication.

One or two users have done a "bare-metal" reinstallation of Windows from scratch, and that seems to have worked (like installing iCloud on a new PC).

Others, like me, used a procedure detailed earlier in this discussion, which involves delving into the depths of Windows to delete files. This worked for some of us, but not for others.

Another procedure that seems to have worked is to uninstall iCloud, then install an earlier version. Some used v.7 and others v.13. Once this installs successfully, some have found that they can then install the MS Store version (v.14).

I hope this may be of some help to you. If you are put off by the suggested 'fixes' you could try contacting Apple Support, but I suspect that most of their Level 1 help people won't have a clue. I spoke to a Level 2 guy who was most helpful, but didn't have a solution at that stage. Or find a friend who's savvy enough to follow the suggested fixes, and do them for you. All the best.

About 3 hours into this problem and nothing. Unistall - install - uninstall - install! Got v.13 and it got stuck after entering Authentication Code... try and retry and nothing. Then try v.14 and after Authentication Code... nothing.

Finally manage to understand all this... but nothing. Still got stuck on the Enter the verification code sent... I enter the code and got an error during authentication. Try with bot v.13 and v.14 and this last want return and error connecting to the Apple ID server.

Hello, just to help you out… the issue to me was significantly different from yours: I never managed to successfully receive the MFA notification on my mobile in order to proceed with the authentication. This means to me that you haven’t been able to solve by the given action plan (by R8000) because your issue is different, not the same that most of users reported on this thread. Hope it helps you to clarify, regards

Noticed was having issues with iCloud not logging in correctly on my Windows 10 Enterprise machine. Loading the iCloud control panel would just spin and give me a log in error. Uninstalled and re-installed iCloud, now getting the “not fully initialized” error when trying to log in. Went through the fixes here with removing certs, not luck for me.

I’m having the same issue on windows 10 Pro. Tried everything from resetting the PC. Clean install. Tried installing iCloud 13.4.101.0, 14.0.162.0, 14.1.108.0 and 14.2.96.0. On all the old versions 2FA works but after a while it gives an error occurred during authentication. On the latest version it does not even ask for 2FA.

I don’t get the message you get. Windows 11 Pro. I am able to sign in to iCloud app but it appears to not fully load into outlook. The “add in” is enabled but contacts & calendars missing. Also missing…..data file (in account settings)…..iCloud tab in menu …..iCloud account on left pane.
