Running Windows 10, getting DLL error code and can't Sync OneDrive Personal

I just spent the weekend cleaning up my OneDrive on our desktop which is Windows 10. My OneDrive Personal ( I do not have Office 365, just the free 100G version) was full, and created space. I also created a few new folders in the OneDrive Personal folder. My intent was to get some items from my hard drive to the cloud so I can start using my new laptop, and scrap the desktop.

After cleaning everything I can't sync and can't start OneDrive in my Explorer. I do see my old files and new files, and can open them with no problem. So, I know the work is there, but maybe only on my hardrive and not the cloud. I did check my other devices and don't see the changes to the OneDrive, but do see the new storage capacity, which is the same on my desktop.

I tried to download the OneDrive App, but get setup error saying a newer version of OneDrive is installed. Says "I need to unistall it first before installing this version. In addition, I also get the DLL error message.

All info found suggests to download, but don't uninstall order version. I can't download due to Version Error. Says to run as administrator.

VERSION ON DESKTOP: 26.012.0199.0002 (467MB with date 2/12/2026)

I don't know how to run as Administrator. HELP!!

I WANT TO MAKE SURE I DON'T LOSE ALL THE CHANGES TO THE ONEDRIVE FILES!

Thanks.

Hello,

The error indicates that the OneDrive program files on your computer are corrupted. Because the system still thinks OneDrive is installed, trying to install it again gives you the "Newer version is installed" error.

To fix this, you must fully uninstall the broken version first.

Don't worry about your files. Uninstalling the OneDrive application will only stop the sync connection. It does not delete the OneDrive folder on your hard drive or the files in the cloud.

Click Start, type Settings, and open it (or click the gear icon). Go to Apps > Apps & features list, look for Microsoft OneDrive, select it and click Uninstall (If asked to allow changes, click Yes). Once uninstalled, download the latest version of OneDrive from the official Microsoft website and install it.

Sign in when prompted, and it will compare your files (Scanning) and resume syncing without losing your data.

    Free OneDrive offers only 5GB of cloud storage.
