A non-responsive double-click on the installer is usually caused by limited Windows account permissions, silent antivirus blocking, or residual background processes. You can quickly restore installation responsiveness by selecting "Run as administrator" or by force-ending old processes in Task Manager. In-depth troubleshooting and solutions: 1. Grant administrator permissions (preferred): Right-click GameBuff_Setup.exe and select "Run as administrator." This bypasses UAC (User Account Control) silent blocking and resolves 90% of unresponsiveness issues. 2. Clear residual background processes: Press Ctrl + Shift + Esc to open Task Manager. In the "Processes" tab, search for any GameBuff-related items. If found, select them and click "End Task," then double-click the installer again. 3. Unblock system file attributes: Right-click the installer -> 【Properties】 -> check if there is a "Security: This file came from another computer..." notice at the bottom. Check "Unblock" and click Apply. 4. Check for environment conflicts: Make sure no other similar modding tools are running simultaneously on your system. It is recommended to temporarily disable Windows Defender Real-time Protection before retrying the installation.
