Dupe Zappa Support
Email support@merginit.com for installation, licensing, billing, refund, or product help.
Do not send personal documents, photos, licence keys, passwords, or other sensitive file contents unless support specifically requests a secure, limited sample. Review screenshots and logs before attaching them.
What to include
- a short description of the problem and what you expected;
- steps that reproduce it;
- the Dupe Zappa version;
- your Windows version;
- relevant error text or privacy-reviewed screenshots;
- for purchases, the order email and order number; and
- whether you purchased directly or through Microsoft Store.
Licence and activation help
Direct purchasers receive a licence key or equivalent entitlement at the email address used at checkout. Check spam or junk folders and the Lemon Squeezy receipt before contacting support.
A direct licence can be active on one device at a time. To move it, open the licence dashboard, sign in with the key, and request the six-digit transfer code sent to the purchase email. The old device may continue offline until its current seven-day entitlement expires. If the purchase email is unavailable, send the order email and order number so support can review the request. Never publish or send a licence key outside a private support conversation.
Billing and refunds
For direct purchases, Lemon Squeezy is the Merchant of Record. The Lemon Squeezy receipt contains transaction and billing support links. MerginIT can help identify the order and coordinate product issues. See the Refund and Withdrawal Policy.
Microsoft Store purchases are managed through the Microsoft account that made the purchase and do not generate a MerginIT licence key.
