If you purchased a digital key or a bundled version like<\/span><a href=\"https:\/\/softwarelizenzexpress.de\/en\/product\/combo1\/\"> <b>Windows 10 Professional + Ms Office 2019 Pro Plus<\/b><\/a><span style=\"font-weight: 400\">, ensure the key was properly delivered and entered.<\/span><\/p>\n<h3><b>To Check:<\/b><\/h3>\n<ol>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Open any Office application (like Word).<\/span><span style=\"font-weight: 400\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Go to <\/span><b>File &gt; Account<\/b><span style=\"font-weight: 400\">.<\/span><span style=\"font-weight: 400\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Look for the <\/span><b>Product Information<\/b><span style=\"font-weight: 400\"> section.<\/span><span style=\"font-weight: 400\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">If you see \"Activation Required,\" click <\/span><b>Change Product Key<\/b><span style=\"font-weight: 400\"> and re-enter it.<\/span><span style=\"font-weight: 400\">\n<p><\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400\">If it fails here, proceed to the next steps.<\/span><\/p>\n<h2><b>Step 2: Run Office as Administrator<\/b><\/h2>\n<p><span style=\"font-weight: 400\">Lack of proper system permissions can prevent activation. Running the Office application with elevated privileges often resolves access errors.<\/span><\/p>\n<h3><b>How to Do It:<\/b><\/h3>\n<ol>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Click the <\/span><b>Start<\/b><span style=\"font-weight: 400\"> menu.<\/span><span style=\"font-weight: 400\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Search for <\/span><b>Word<\/b><span style=\"font-weight: 400\"> or any Office app.<\/span><span style=\"font-weight: 400\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Right-click the app and select <\/span><b>Run as administrator<\/b><span style=\"font-weight: 400\">.<\/span><span style=\"font-weight: 400\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Attempt activation again.<\/span><span style=\"font-weight: 400\">\n<p><\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400\">If successful, it will register the license without prompting again.<\/span><\/p>\n<h2><b>Step 3: Disable Antivirus or Firewall Temporarily<\/b><\/h2>\n<p><span style=\"font-weight: 400\">Third-party antivirus programs or strict firewall settings can block Office from reaching Microsoft's activation servers.
