tl;dr: No matter, what I do, I can't access OneDrive folder on my Windows 8.1-based PC. I have tried a number of different approaches (explained in details below) and still ended up with nothing. Is there anything else, I can do, except for reinstalling whole Windows 8.1 or trying any 3rd-party software?
I have installed Windows 8.1 on my wife's computer in June 2014 and I did something (after 1,5 year I simply don't remember what) to completely rip OneDrive off the Windows. She was using her PC and Windows 8.1 for one year and a half without any problems, but now I'd like to start using OneDrive. The problem is, that there is no sign of it on that PC.
Virtually any guide, that I have been reading for past three hours stars with clicking "OneDrive" icon in taskbar or on file browser. But, the problem is, that I don't have that icons there.
Symptoms or steps already undertaken by me:
Download and installation of OneDrive client is not an option, because OneDrive is (should be in my case) integrated into Windows 8.1. Installer starts and ends without any message or error.
SkyDrivefrom command-line with or without parameters brings absolutely no effect.
I have Windows 8.1 Home Edition, Polish, up to date (with all Windows Update updates installed). My wife has been using local account for 1,5 year. I have switched it to Microsoft account today, but this also brought no effect.
Any regular OneDrive troubleshooting guides or FAQs (like this one, this, this one or maybe this) is not an option for me, because it starts with "Right-click the OneDrive icon..." and I don't have a OneDrive icon anywhere within my Windows 8.1 (not in task bar and not in file explorer).
Running OneDrive Troubleshooter ends with error, that OneDrive folder is not accessible.
Searching for OneDrive icon in classic shell and executing it ends up with empty, white screen (named "OneDrive") and never-ending loader bar moving in the top. I can access OneDrive settings from Control Panel, but can't access OneDrive files / folder itself.
As above, searching for OneDrive icon in classic shell, right-clicking it, pinning it to task bar and then trying to execute it from there ends up
c:\Windows\FileManager\FileManager.exe's runtime error "The application has requested Runtime to terminate in an unusual way".
Because of point (6) above, I've tried to use guides like this one, this or this one to recreate (or check) OneDrive default folder on my PC or to force-rune OneDrive client from it. It brought no effect, again.
I have folders
C:\Users\[username]\OneDriveas well as
%localappdata%\Microsoft\OneDrive\, by any mean (Start > Run, Pin to Task bar, command-line, Send to Desktop) brings no effect (no window, no error, no icon in task bar or in file explorer).
C:\Users\[username]\OneDrive are empty. Folder
%localappdata%\Microsoft\OneDrive\ has a number of files and sub-folders, all with date set to today, about three hours ago, thus they all should be up-to-date (newest version of OneDrive?).
It seems for me, that I have checked everything, I can think of, and still ended up with nothing.
Edit: I have upgraded my computer to Windows 10 and problem was solved for me -- I have now full access to OneDrive. However, for the sake of community (i.e. others having the same problem), I strive to receive any answer to this question.
