Chrome “Your Preferences Can’t Be Read” Error Fix

The “Your preferences can’t be read” message usually means Chrome cannot access or use its profile settings file. You can often fix it by closing Chrome, backing up the affected profile, and letting Chrome create a fresh preferences file; start with the least disruptive checks to protect bookmarks and other data.

What You’ll Need

• Access to the computer account where the error appears.
• A few minutes with Chrome fully closed.
• Optional: a file manager and permission to rename or move files in your Chrome profile folder.
• If practical, a backup of important bookmarks or other data before changing profile files.

Step-by-Step

1. Close Chrome completely. Close every Chrome window. On Windows, press Ctrl+Shift+Esc to open Task Manager, select any remaining Google Chrome processes, and choose End task. On macOS, use Chrome > Quit Google Chrome, then check Activity Monitor if it appears to remain open. On Linux, quit Chrome and check the system monitor if needed. Do not edit profile files while Chrome is running.
2. Restart the computer and try again. A background process or temporary file lock can prevent Chrome from reading its settings. After restarting, open Chrome once. If the error is gone, there is no need to change the profile. If it remains, close Chrome completely again.
3. Check available storage and account access. Make sure the system drive is not full. Confirm you are signed in to the usual computer account and can create or edit files in your own user folders. If Chrome is installed or managed by an organization, ask its administrator before changing files or permissions.
4. Find the Chrome profile folder. Common locations are:
   • Windows: %LOCALAPPDATA%\Google\Chrome\User Data
   • macOS: ~/Library/Application Support/Google/Chrome
   • Linux: ~/.config/google-chrome (some installations use a different Chrome data directory).

   On Windows, paste the path into File Explorer’s address bar. On macOS, in Finder choose Go > Go to Folder and enter the path. The tilde (~) on macOS and Linux represents your home folder. If the folder is not there, do not create a new one blindly; Chrome may be using a different profile or installation.

5. Back up the profile before changing it. In the profile folder, identify Default or the relevant profile folder, such as Profile 1. Copy that entire folder to a separate, safe location, such as an external drive. Profiles may hold bookmarks, history, extensions, and local settings. If you cannot make a backup, stop here and try the less invasive options in Troubleshooting first.
6. Rename only the Preferences file. Open the relevant profile folder and locate the file named Preferences (it may not have a visible extension). Rename it to Preferences.old. Do not delete the whole profile folder, and do not rename similarly named files such as Secure Preferences or files in another profile. If your system says the file is in use, Chrome is still running; close it before continuing.
7. Open Chrome and check the result. Chrome should make a new Preferences file when it starts. Check whether the message has disappeared and whether the correct profile opens. Some local settings may return to defaults; review settings and extensions. If Chrome still reports the error, close it and follow the troubleshooting section rather than repeatedly renaming files.
8. Restore the old file if the change causes a problem. Quit Chrome fully. If the new Preferences file exists, move it aside as Preferences.new, then rename Preferences.old back to Preferences. Reopen Chrome. Restoring the file can also restore the original error, but it returns the profile to its prior state while you consider another option.

Common Mistakes

• Deleting the whole User Data folder. This can remove local profile information and is not a first-line fix. Back up before any broader reset.
• Editing files while Chrome is open. Chrome may overwrite your change or keep the file locked. Quit all processes first.
• Changing the wrong profile. If several profiles exist, verify which one is affected. Do not assume Default is the active profile.
• Assuming sync is a complete backup. Sync may not include every local setting or file. Confirm important data is backed up separately before resetting a profile.
• Changing folder permissions broadly. Avoid making your entire user folder writable by everyone or running Chrome as an administrator to bypass access problems. Correct only a confirmed ownership or permission issue, preferably with help from an administrator.

Tips

• Renaming a file rather than deleting it makes the change reversible.
• Keep the backup outside the Chrome profile directory, so a profile reset or cleanup will not remove it.
• If Chrome opens after the fix, check bookmarks and other important data before removing any backup or old file.
• For a work or school device, managed settings may be restored by policy. Contact the administrator rather than trying to override them.

Troubleshooting

The Preferences file is missing. Do not create an empty replacement. Check that you are in the correct profile folder and that hidden files are visible if needed. If Chrome continues to show the message, create a new Chrome profile using Chrome’s profile menu, if available, and see whether it opens normally. Keep the original profile untouched.

You cannot rename or copy the file. Make sure Chrome is fully closed and that the file is not being used by another process. Check free disk space and that you can write to your own profile folder. On a managed computer, ask the administrator; avoid changing system-wide permissions as a workaround.

The error returns after Chrome recreates Preferences. Another issue may be preventing Chrome from saving the file, such as insufficient disk space, a file-system problem, or security software interfering with profile access. Check storage, restart, and consult the security software’s logs or administrator. Do not disable protection wholesale. You can also test a new Chrome profile; if that works, the original profile is likely damaged.

A new profile works, but you need data from the old one. Keep both profiles and use Chrome’s available export or import options for items such as bookmarks. Avoid copying the entire old profile over the new one, since that can bring back the damaged settings. If important data is unavailable, preserve the backup and seek technical support before resetting or removing the old profile.

Chrome will not open at all. Restart the computer, check that Chrome is not still running, and confirm the system drive has space. If the issue persists, use the operating system’s normal app repair or reinstall process, where available, without deleting user data. Back up the profile folder first.

Frequently Asked Questions

Will renaming Preferences delete my bookmarks?
It normally targets settings in that profile, not the separate bookmarks file, but profile data can be at risk during troubleshooting. Back up the profile first and verify bookmarks afterward.

Will I be signed out of Chrome?
You may need to review settings or sign in again, depending on what Chrome can recover. Do not count on sync to restore every local preference.

Should I delete the Secure Preferences file too?
No—not as a routine step. The safer first test is to rename only the affected profile’s Preferences file. If the error remains, investigate the profile or permissions rather than deleting more files.

Can I fix this by reinstalling Chrome?
Reinstalling may help if the application itself is damaged, but it may not fix a problem in the user profile. Back up profile data and try the targeted steps first.

Is it safe to delete Preferences.old later?
Only after Chrome works as expected and you have checked that important data is available. Keep the backup until you are confident it is no longer needed.

What if the error affects every Chrome profile?
Check disk space, account permissions, security software, and whether Chrome is managed by an organization. If the problem continues across new profiles, consider app repair or support from your device administrator.
