Warning: Only use this method if you are comfortable editing the Windows Registry. Incorrect changes can affect system stability.

If the files are gone but the error persists, the "partially deleted" flag is living in your Registry.

💡 Pro Tip: If you recently switched from "Backup and Sync" to "Drive for Desktop," this error is very common. Ensure you have manually uninstalled "Backup and Sync" via the Control Panel before trying to install the new "Drive for Desktop" app, as they often conflict with each other.

The Mysterious Case of the Half-Deleted Installation

It was a typical Monday morning for John, a freelance writer who relied heavily on Google Drive to store his files and collaborate with clients. As he booted up his computer and opened Google Drive, he was greeted with a frustrating error message:

"A partially deleted previous installation was detected. Please uninstall and reinstall Google Drive to resolve the issue."

John was perplexed. He had no recollection of deleting any Google Drive installations, and he was certain he had always kept his software up to date. He tried to ignore the message and access his files, but Google Drive wouldn't sync properly, and he couldn't access his crucial documents.

Desperate to meet a looming deadline, John decided to investigate further. He navigated to the Google Drive folder on his computer and noticed a strange, hidden folder named ".google-drive-temp". Curious, he opened the folder and found a mishmash of files and subfolders with cryptic names.

John suspected that this mysterious folder might be the remnants of a previous Google Drive installation, but he had no idea how it got there or what had caused the error. He tried to delete the folder, but his computer refused, citing permissions issues.

The Search for a Solution

John spent the next few hours scouring the internet for solutions. He visited Google's support forums, Reddit, and various tech blogs, but none of the suggested fixes worked. Some users recommended running a registry cleaner, while others suggested reinstalling Google Drive with administrator privileges. John tried them all, but the error persisted.

As the hours ticked by, John's frustration grew. He was on the verge of giving up when he stumbled upon a Google Support page that mentioned a possible cause of the issue: a conflict between Google Drive and a third-party backup tool.

John remembered that he had installed a backup software, Backup Exec, a few months ago to backup his external hard drive. He suspected that this software might be interfering with Google Drive. He quickly uninstalled Backup Exec and restarted his computer.

The Resolution

With a glimmer of hope, John reopened Google Drive and was relieved to see that the error message had disappeared. The software began to sync his files properly, and he could access his documents once again.

To ensure that the issue was fully resolved, John reinstalled Google Drive, this time using the "Advanced" installation option, which allowed him to specify a custom installation location. He also made sure to exclude the ".google-drive-temp" folder from any future backups.

With his Google Drive up and running smoothly, John breathed a sigh of relief. He learned a valuable lesson about the importance of keeping his software and backup tools in harmony. From then on, he made sure to regularly review his installed software and backup configurations to prevent similar issues in the future.

The Takeaway

The "partially deleted previous installation" error on Google Drive might seem daunting, but it's often caused by conflicts with other software or leftover files from previous installations. By methodically troubleshooting the issue and using the right tools, John was able to resolve the problem and get back to work. If you're facing a similar issue, don't hesitate to try the following:

By following these steps, you should be able to resolve the issue and get your Google Drive up and running smoothly.

The error message "A partially deleted previous installation was detected" typically occurs when residual files or registry keys from a failed uninstallation prevent a fresh install of Google Drive for desktop.

To resolve this, follow these steps to manually clean up your system: 1. Clear Pending Operations Often, Windows is waiting to finalize a file deletion.

Reboot your computer first; this solves the issue for many users.

If the error persists, try running the installer with a special flag: Open Command Prompt (cmd.exe). Navigate to your Downloads folder: cd Downloads

Run the installer by typing: GoogleDriveSetup.exe -skip_version_check. 2. Manually Delete Residual Folders

Residual "DriveFS" folders are the most common culprits. Delete these specific directories if they exist: %USERPROFILE%\AppData\Local\Google\DriveFS C:\Program Files\Google\Drive File Stream (or just Drive) 3. Clean the Windows Registry

Warning: Be careful when editing the registry. Incorrect changes can harm your system. Press Win + R, type regedit, and hit Enter. Search for and delete these keys if they remain: HKEY_CURRENT_USER\Software\Google\DriveFS HKEY_LOCAL_MACHINE\Software\Google\DriveFS

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Google\Update\ClientState\6BBAE539-2232-434A-A4E5-9A33560C6283 4. Remove Persistent Drivers

If you cannot delete certain files like googledrivefs.sys because they are "in use": Restart into Safe Mode.

Navigate to C:\Program Files\Google\Drive File Stream\Drivers and delete the contents. Reboot normally and attempt the installation again.

Regarding the "long feature" or "long filename" issue, ensure your Google Drive folder is not nested in extremely deep subdirectories, as Windows has a 255-character limit for file paths which can cause syncing and installation errors.

Title: Fix: “A Partially Deleted Previous Installation Was Detected” in Google Drive for Desktop

Post:

If you’re trying to install or reinstall Google Drive for desktop and get the error:

“A partially deleted previous installation was detected. Please reboot your machine and run the installation again.”

Don’t worry — this is a common issue, usually caused by leftover registry entries, files, or services from a previous incomplete uninstall.

  • Run official uninstaller (Control Panel → Programs and Features) if available; choose Repair or Uninstall.
  • If uninstaller not present or fails, manually remove leftover directories:
  • Remove stale service entries:
  • Clean registry references (advanced, backup registry first):
  • Clear installer temp/cache:
  • Reboot and run the latest Drive for desktop installer (download fresh copy from Google).
  • After install, verify service is running and Drive mounts/syncs correctly.
