Activation questions tend to come as "If I see this, what 1[833][631][3616]do I do?" So this guide is an if-then rulebook. Each rule starts 1[833][631][3616]with what you see and ends with what you do. Find the rule 1[833][631][3616]that matches your screen. The Core Run When Everything Goes Right 1[833][631][3616]1 Find your order email search "Emsisoft", "licence key", "order", "receipt", including spam. 1[833][631][3616]2 Uninstall other antivirus programs and restart. 3 Download Emsisoft from the official 1[833][631][3616]site typed yourself, or from your order email. 4 Right-click the installer and 1[833][631][3616]choose Run as administrator. 5 Open Emsisoft and choose Activate, Enter licence key 1[833][631][3616]or the licence option. 6 Enter the key exactly as written and confirm. 1[833][631][3616]7 Check that the plan and expiry date appear. The Rulebook 1[833][631][3616]IF you can't find the key, THEN search all your email addresses for 1[833][631][3616]"Emsisoft" including spam, check the order confirmation page, and sign in to your 1[833][631][3616]My Emsisoft account to see if the licence is listed. If not, contact 1[833][631][3616]Emsisoft support with your payment details. IF the program says "Invalid key", 1[833][631][3616]THEN retype it slowly, check O and 0, and I and 1, and 1[833][631][3616]remove spaces at the start and end. IF the key is accepted 1[833][631][3616]but you see a trial, THEN restart the program, check the internet and 1[833][631][3616]look at the licence page for the plan. IF it says the 1[833][631][3616]key is "already in use" or the device limit is reached, THEN open 1[833][631][3616]your account or licence list, remove a device you no longer use and 1[833][631][3616]try again. IF the key belongs to a different edition, THEN install 1[833][631][3616]the edition that matches your order email, because a key for one edition 1[833][631][3616]usually won't unlock another. IF the installer is blocked or won't start, 1[833][631][3616]THEN download it again from the official site, run it as administrator, and 1[833][631][3616]allow it if your security warns about it after you've checked it is 1[833][631][3616]the official file. IF your old antivirus is still installed, THEN uninstall 1[833][631][3616]it, restart and install Emsisoft again.

IF you bought for a business with several devices, 1[833][631][3616]THEN follow your administrator's instructions or your organisation's console, because business licences are 1[833][631][3616]managed differently from home ones. IF you got a call or pop-up 1[833][631][3616]telling you to ring a number to activate, THEN close it. That's a 1[833][631][3616]scam, and activation never needs remote access.
