It seems like the issue with Spine not launching on your new PC could be related to interference from other software, such as antivirus or security programs, or possibly missing dependencies. Here are some steps you can try to resolve the issue:

  1. Antivirus/Security Software: Check if any antivirus or security software is running on your system. Temporarily disable it or add Spine to the exceptions list to see if that resolves the issue. Some software, like Sentinel One, is known to interfere with Spine.

  2. Reinstall Spine: Download the latest version of the Spine launcher from your license page and reinstall it. This can help if the installation was corrupted or if there are missing dependencies.

  3. Run as Administrator: Try running Spine as an administrator. Right-click on the Spine executable and select "Run as administrator" to see if it launches.

  4. Check for Missing Dependencies: Ensure that all necessary dependencies, such as Microsoft Visual C++ Redistributables, are installed. You can download them from the Microsoft website.

  5. Command Line Execution: Open a command prompt and navigate to the Spine installation directory. Run Spine.com to see if any error messages are displayed, which might give more insight into the issue.

  6. Graphics Drivers: Make sure your graphics drivers are up to date, as outdated drivers can sometimes cause issues with software launching.

If these steps do not resolve the issue, it might be worth checking for any other software that could be interfering with Spine's operation.
