How to Fix the SolidWorks Toolbox and Material Database Error After an Update

Common issues with Toolbox and the Material Database

SolidWorks users frequently experience errors when trying to insert Toolbox components (screws, nuts, etc.) or modify material properties after a software update. The most common error messages include:

• "The Toolbox file is read-only"
• "Material database not found"
• "Unable to save changes to material properties"

Main causes

These issues generally occur due to:

1. Incorrect file paths in System Options after the update
2. Insufficient write permissions on the shared Toolbox folder
3. File attributes marked as "read-only"
4. Network configurations that block access to the database

How to fix Toolbox and Material issues

1. Reconfigure the file paths

Step by step:

1. Open SolidWorks and go to Options > System Options.
2. Select the File Locations tab.
3. Look for the entries for Toolbox and Material Database.
4. Verify that the paths point to the correct locations:
   • The typical Toolbox path is: C:ProgramDataSOLIDWORKSSOLIDWORKS [versión]Toolbox
   • The material database is normally located at: C:Program FilesSOLIDWORKS CorpSOLIDWORKSlang[idioma]sldmaterials.mdb
5. If the paths are incorrect, click Browse to navigate to the correct location.
6. Save the changes and restart SolidWorks.

2. Fix file permissions and attributes

For files marked as "read-only":

1. Open Windows Explorer and navigate to the Toolbox folder.
2. Select all the files (.sldprt, .sldlfp, etc.) and right-click.
3. Select Properties.
4. On the General tab, uncheck the Read-only box.
5. Apply the changes to all files and subfolders.

To fix permissions:

1. Right-click the Toolbox folder > Properties.
2. Go to the Security tab.
3. Click Edit to modify the permissions.
4. Make sure the Everyone group or your user account has Full Control permissions, or at least Modify.
5. Apply the changes and click OK.

3. Solution for network environments

If Toolbox is located on a shared server:

• Verify that all users have write access to the shared folder.
• Properly configure shared and NTFS security permissions (see the Microsoft guide on ICACLS).
• Consider using the SolidWorks Toolbox Settings tool to configure multi-user access.

Frequently Asked Questions (FAQ)

What should I do if I can’t find the Toolbox folder after updating?

The update may have created a new folder for the new version. Check C:ProgramDataSOLIDWORKS for the folders of different versions.

How do I recover custom materials after a database error?

Follow this official procedure to restore from a backup.

Why do permission issues reappear after fixing them?

This may be caused by network group policies that reset permissions. Check with your system administrator.

Is it safe to manually modify the material .mdb files?

This is not recommended. Always use the SolidWorks interface or official tools to modify the database.
