Ensure you have internet connection so that the TestComplete can communicate with the license server, ensure you can access the servers (as mentioned in the links) and it's not being blocked by your firewall.

It looks like the missing file (testcomplete15.chm) is not the real cause — TestComplete can run without it. The symptoms you’re seeing (“token expired” followed by “unverified login”) usually point to issues with SmartBear ID-based licensing being unable to verify or refresh the authentication token.

A few things to check:

1. Validate communication with SmartBear licensing servers TestComplete must be able to reach SmartBear’s ID-based licensing endpoints. If your firewall, proxy, or VPN blocks access, the token cannot refresh and you’ll see “token expired.”

2. Verify your Windows system clock. If the system time, timezone, or NTP sync is off, TestComplete treats authentication tokens as expired. Even a small time drift can cause “token expired” or “unverified login.” https://support.smartbear.com/testcomplete/docs/licensing/key-based/troubleshooting/the-system-time-on-your-computer-has-been-changed.html 

3. Clear locally cached SmartBear licensing and credential data. Sometimes the cached SmartBear ID token or local licensing files become corrupted. You can clear them by:

• Closing TestComplete
• Opening Windows Credential Manager → Generic Credentials and removing any SmartBear / TestComplete entries
• Deleting local cache files under:C:\ProgramData\SmartBear\Identity\ C:\ProgramData\SmartBear\Licensing\(Do not delete the folders—just the files inside)

After clearing these, restart TestComplete and sign into your SmartBear ID again.
