6. Rollback Procedure (if update fails)

If WinOLS 4.7 causes critical issues:

1. Uninstall WinOLS via Control Panel → Programs and Features.
2. Delete leftover C:\Program Files\WinOLS (after backup).
3. Restore from backup: Copy back your saved Projects and User folders.
4. Reinstall WinOLS 4.6 from original installer.
5. Restore license via Help → License Transfer (if using software license).

6. Post-Installation Configuration

• Set default working directory: Options → Paths → set folder for projects, maps, OLS files.
• Checksum correction: Enable Automatic checksum correction in Options → Checksum.
• Hardware interface: Configure under Options → Hardware for your OBD tool.

Error 1: "Failed to load checksum library (Error code: 0x80070005)"

• Cause: Permission issue. Windows blocked the CRC database.
• Fix: Navigate to C:\WinOLS\System\Checksums. Right-click the folder → Properties → Security → Give "Everyone" Full Control. Re-run WinOLS as Admin.

4) Activate license (common methods)

• USB dongle: Plug the dongle into a USB port before launching WinOLS; install any vendor-supplied driver; WinOLS should detect the dongle automatically.
• License file/key: Use WinOLS’ license manager (Help or License menu) to import the license file or enter the activation key. Follow on-screen prompts; you may need internet access.
• Online activation: If the installer offers an online activation flow, allow it to contact the vendor servers. If your network restricts outbound connections, use an offline activation option provided by the vendor.
