That “OneDriveSetup.exe – Entry Point Not Found” error is pretty annoying, especially if you rely on OneDrive for storing stuff. It pops up because the installer can’t access certain system functions — either because they’re missing, corrupted, or simply outdated on your system. This tends to happen more on older Windows versions like Win 7 or 8, especially if updates weren’t installed properly or got interrupted. Sometimes, background conflicts or partial updates mess with it too. Anyway, here are some tried-and-true fixes for that error, so you spend less time fighting and more time actually syncing.
How to Fix “Entry Point Not Found” Error in OneDrive
Method 1: Install the Missing System Update KB3080149 (For Windows 7 and 8)
This update adds essential system libraries that older Windows versions lack, which are kinda necessary for apps like OneDrive. If the libraries are missing, the installer throws that error. It’s a bit old school but easy to fix.
- Head over to the Microsoft Update Catalog. Search for KB3080149.
- Pick the right version — 32-bit or 64-bit. To check if you have 64-bit or 32-bit Windows, press Win + Pause/Break, then look under System type.
- Download the installer, then run it and follow the prompts. Be patient — sometimes it takes a minute or two, especially on older hardware.
- Reboot after it finishes, and try installing or running OneDrive again.
On some setups, this update fails the first time, but after a reboot, it works fine. Because Windows loves to make everything more complicated than it should be.
Method 2: Reset OneDrive to Clear Corrupted Cache
If this error keeps popping after update, resetting OneDrive clears out cached data that might be causing issues without deleting your files. It’s kind of a magic trick sometimes.
- Hit Win + R to open the Run dialog.
- Type this command and press Enter:
%localappdata%\Microsoft\OneDrive\onedrive.exe /reset - If you get the message “Windows cannot find…” — don’t worry, try this alternative instead:
- Type:
C:\Program Files\Microsoft OneDrive\onedrive.exe /reset - Now wait a couple of minutes. OneDrive might restart automatically once the reset finishes. If not, look for the icon and manually start it again from the Start menu or search.
- If that still doesn’t do the trick, you might need to uninstall and reinstall.
Sometimes, this reset fixes strange errors — on one machine it worked right away, on another, a reboot might be needed. OneDrive has a mind of its own.
Method 3: Reinstall OneDrive Completely
This is the nuclear option but worth it if the app’s real knackered. Back up any files you haven’t synced yet, just in case. Then, clean out the old files and install fresh.
- Press Win + R, type
appwiz.cpl, and press Enter. This brings up the Programs list. - Locate Microsoft OneDrive, right-click, and choose Uninstall. Follow the prompts to remove it completely.
- Go to the Microsoft OneDrive download page and grab the latest installer.
- Run the setup file, follow the instructions, and sign in again. Fingers crossed, this resets all the broken bits.
Yes, sometimes it just works better to start fresh. Not sure why, but on some machines, a clean install makes all the difference.
Method 4: Disable the Automatic Update Task (For Old Windows Systems)
Old versions of Windows sometimes have this sneaky task that updates OneDrive in the background — which can conflict with the app or cause errors. Disabling it might help stop the error from popping up.
- Open Task Scheduler by pressing Win + R, typing
taskschd.msc, and hitting Enter. - Navigate to Task Scheduler Library > Microsoft > OneDrive.
- Right-click on OneDrive Standalone Update Task and select Disable.
This prevents automatic updates from messing with your current setup, at least on older Windows. On newer versions, this step might not do much.
