- A screenshot of any activation error, if applicable.
- The OS version (for Windows / Office issues).

Frequently asked
- What's the fastest way to reach support?
- Email support@licensevault.net with your order number in the subject line. Median first-response time is under 2 hours, 24/7.
- Do you offer phone or live chat?
- We're a digital-delivery business and intentionally don't run phone support — it lets us keep prices low and response times high. Every issue is handled by a licensing specialist over email.
- I can't activate my key — what do I do?
- Reply to your order email with a screenshot of the error. If the key has truly failed activation, we replace it free of charge under our lifetime guarantee, usually within an hour. See /help/activation for the most common error codes.
- Do you handle volume / business orders?
- Yes. For 25+ seats or any Microsoft 365 Business / Windows Server / SQL Server volume order, email sales@licensevault.net for a custom quote and invoice with VAT.
- How do I report a security issue?
- Email security@licensevault.net. We acknowledge within 24 hours and do not pursue legal action against good-faith researchers acting under coordinated disclosure.
- How do I exercise my GDPR rights?
- Email privacy@licensevault.net with the email used on your order. We respond within 30 days. See the /privacy page for the full list of rights.
- Can I get an invoice with a different company name?
- Yes, before delivery. After delivery, invoices can only be re-issued with the same name on the original order for VAT-trail reasons.
