Analysis: "WinOLS 2.24 error load DLL"

Summary

Case 3: The Corrupted Project File

User error: Error only appears when opening a specific .ols project file. Cause: The project file contained a reference to a plugin DLL that no longer exists. Solution: Opened WinOLS in safe mode (hold Ctrl+Shift while launching), disabled auto-load plugins, then opened the project and removed the broken plugin reference.

Phase 3: File Validation & Reinstallation

If the error persists, the installation is likely corrupt.

When to contact vendor/support

  1. Find the original WinOLS.exe in its installation directory.
  2. Double-click it directly. Does the error still appear?
  3. If it works fine from there, delete the old shortcut and create a new one: Right-click WinOLS.exe > Send to > Desktop (create shortcut).
  4. Then edit the new shortcut: Right-click > Properties. Ensure the "Start in:" field is empty or set to the absolute path of the WinOLS folder.
