When you purchase EmEditor, you receive a registration key. This key unlocks the software from "Evaluation Mode" to a fully registered version.

Using a pirated key violates copyright law and Emurasoft’s EULA. While individual users rarely face lawsuits, businesses can be audited and fined heavily.

Q: Can I use one EmEditor key on my desktop and laptop? A: The standard license is for one PC at a time. However, if you use them alternately (not simultaneously), Emurasoft is lenient. For concurrent use, buy a 2-PC pack.

Q: Does EmEditor expire if I don’t enter a key? A: Yes, after 30 days, the Professional version enters reduced functionality mode (or stops opening files over a certain size).

Q: Is an EmEditor key reusable after uninstalling? A: Yes, as long as you have not exceeded activations. Always deactivate first (Help -> Deactivate) before a major OS reinstall.

Q: Are there student discounts for an EmEditor key? A: Yes. Email support with proof of student status for a 20-30% discount code.

If you absolutely cannot afford a $40 license, consider these legal options instead of stealing:

If you have purchased EmEditor but lost your key:


One of EmEditor's standout features is vertical editing (multi-caret), allowing you to type on multiple lines simultaneously.

EmEditor is also available on the Microsoft Store and Steam. Keys purchased there are tied to your Microsoft or Steam account rather than provided as an independent alphanumeric key. However, these still function as valid licenses.

A cracked key cannot download official updates from emeditor.com. You will miss critical security patches and new features (e.g., Dark Mode, ARM64 support).
