How to Repair: Google Drive “Error Loading Python DLL” Issue

Google LLC developed and launched Google Drive as file storage and synchronization service on April 24, 2012. The three main functions of Google Drive are storing files on servers, synchronizing files between devices, and sharing files with other users. Google Drive also offers apps with offline functionality for users of various devices (Windows and macOS-based computers, Android and iOS smartphones, and tablets).

Like all other programs and services, Google Drive suffers from various errors. For example, Python DLL load error is a typical fatal Google Drive error that people may encounter.

If you are also facing this error, here are some troubleshooting tips to help you fix the “Error loading Python DLL” error in Windows.

What causes the “Error loading Python DLL” message in Google Drive?

  • The executable does not have administrator access: This particular error (as well as general application instability) can also be fixed by making sure that the executable does not have administrator access. This prevents the Google Sync app from maintaining a persistent connection to Google Drive.
  • Backup and Sync version is incompatible with the Windows version: Another possible cause that can lead to this scenario is a scenario where the GoogleDriveSync.exe executable file is actually incompatible with the Windows version. This can happen if you are using an outdated backup and sync application.
  • Permission issue: This error message may be caused by a permission issue that prevents the synchronization feature of the Backup and Sync application from communicating properly with the Drive servers.
  • Outdated version of Backup and Sync: Another possible cause of this problem is a very outdated version of the Backup and Sync application.
  • Temporary folder contains corrupt Drive files: It turns out that interruptions in the process of synchronizing local data with Google Drive cloud can lead to permanently corrupted files that essentially destroy applications.
