This message confirms that your WinOLS license activation or update is complete, but the changes will not take effect until the program is fully reloaded. It is a standard part of the registration process. Immediate Actions
Close and Relaunch: Completely exit the WinOLS application. Ensure it is not running in the background via the Task Manager if it doesn't close immediately. ✅ WinOLS install key completed
Verify Activation: Upon restarting, navigate to Help > About or check the bottom status bar. Your customer number or registered name should now be visible, indicating the full version is active.
Check for Updates: WinOLS often prompts for a secondary update immediately after a fresh activation to ensure you have the latest checksum modules and ECU definitions. Common Post-Restart Troubleshooting If the software still asks for a key after restarting:
Run as Administrator: Right-click the WinOLS icon and select "Run as Administrator" for the first launch after activation. This allows the software to write the necessary license files to protected system folders.
Firewall/Antivirus: Ensure that WinOLS is whitelisted in your firewall. The software must connect to the EVC server to validate the license key.

Frequently Asked Questions
Q: Does "install key completed restart app" mean my WinOLS license is permanently damaged? A: No. It is typically a communication glitch between the installer and the main program. Your license key file or dongle is almost certainly intact.
Q: Can I ignore the restart and keep using WinOLS? A: Only if the key was already active before. If you just installed a new key, ignoring the restart means WinOLS will run in demo mode (limited functionality).
Q: How long should I wait after restarting the app? A: Give WinOLS up to 30 seconds after restart. Some dongle drivers perform background handshakes. If the splash screen freezes, restart your PC.
Q: Does Windows 11 cause more of these issues than Windows 10? A: Yes. Windows 11 has stricter driver signature enforcement and virtualization-based security (VBS). You may need to disable Memory Integrity (Core Isolation) in Windows Security settings to allow WinOLS dongle drivers to load.

Common Causes of the Loop: "Install Key Completed Restart App" Won't Go Away
Users frequently report that after restarting WinOLS, the same message appears again, or the key remains invalid. Here are the root causes:
Step-by-Step: What to Do Next
When this prompt appears, follow these precise steps to ensure the license is recognized.
3. Corrupted User Profile or Registry Entries
If you previously installed an older version or a cracked version of WinOLS, residual registry keys can conflict with the new license. The installer thinks the key is present, but the validation fails at runtime.
2. Run as Administrator (Crucial)
This is the most common reason why the "restart" fails to activate the software.
- Locate the WinOLS icon on your desktop or start menu.
- Right-click the icon.
- Select "Run as Administrator."
- Note: Even if you are logged in as an admin, User Account Control (UAC) can prevent the software from reading the license file correctly unless explicitly elevated.
