The "Error: Cannot initialize library" message in SOLIDWORKS 2012 typically occurs during software activation or when accessing specific features like the Toolbox. Common Fixes
Re-register System Files: Use the command prompt as an administrator to re-register the DLL files that control these libraries. Use the command regsvr32 [filename].dll for files like Ole32.dll if they are corrupted.
Verify Toolbox Settings: If the error occurs when using the Hole Wizard or Toolbox, it often means the SWBrowser.mdb database file is missing. Go to Tools > Options.
Select Hole Wizard/Toolbox from the System Options tab to ensure the file path is correct.
Run Compatibility Tools: If you are using a 64-bit system, ensure the library components are 64-bit compatible. Some older versions may require running specific setup programs found in the installation folder to initialize the environment properly. error cannot initialize library solidworks 2012

Corrupted Registry Entries: Issues with Windows registry keys can prevent the COM library from initializing properly.
Database Path Issues: Upgrading from a previous version (e.g., 2011 to 2012) can break links to the Toolbox library if the folder location was changed.
