Insufficient permissions prevent the launcher executable from spinning up necessary services.<\/p>\n<ul style=\"padding-left: 20px;\">\n<li>Navigate to your game directory (e.g., <code>C:\\Program Files (x86)\\Call of Duty<\/code>).<\/li>\n<li>Right-click <strong>cod.exe<\/strong> (or your launcher executable) and click <strong>Properties<\/strong>.<\/li>\n<li>Select the <strong>Compatibility<\/strong> tab.<\/li>\n<li>Check the box for <strong>Run this program as an administrator<\/strong>.<\/li>\n<li>Click <strong>Apply<\/strong> and restart your PC.<\/li>\n<\/ul>\n<h3 style=\"color: #c2410c; font-size: 19px; font-weight: 600; margin-top: 24px;\">Method 2: Verify Game File Integrity (Steam &amp; Battle.net)<\/h3>\n<p>Incomplete updates or interrupted downloads routinely corrupt vital engine DLLs.
