Troubleshoot MacKeeper Activation Errors

Sometimes, when you install and activate MacKeeper, you run into errors during or after the process. Here’s a quick guide to troubleshooting the most common activation errors you may face while installing and activating MacKeeper.

Error 1: Activation Code Already in Use

While activating my MacKeeper license, I got this message: “Activation code has already been applied to your other MacKeeper account. Please log in.”

Now, I didn’t have any other account, so it took me a while to figure this one out, but here’s how you can log back into your MacKeeper account:

  1. Click the small Profile icon in the top left corner of your MacKeeper window.
click the small profile icon in mackeeper
  1. Click Log Out.
click log out in mackeeper
  1. Next, log in with your email and password.
  2. Your valid MacKeeper license will be automatically activated.

Error 2: Invalid Activation Code

Oops! Invalid activation code? If you see a message like “Your activation code is not valid,” here’s what to do:

  1. First, double-check if you’ve entered the code correctly. Remember, a valid MacKeeper activation code should be 16 characters long and a mix of letters and numbers.
  2. Next, ensure you’ve copied the entire code when pasting it. Find that MacKeeper order confirmation email in your mailbox, and copy your activation code carefully. Then, paste it again.

Error 3: Activation Server Unavailable

When this error occurs, you get the “Activation server is unavailable. Please try again later” message. This error can occur if the MacKeeper activation server is down or experiencing technical difficulties.

Try activating your MacKeeper license again later. If the error persists, contact MacKeeper support for assistance.

Error 4: Activation Limit Exceeded

If you see the “Activation limit exceeded” message, it means your MacKeeper license is already active on too many devices. MacKeeper licenses have a limit on the number of devices they can be used on.

To fix this, deactivate the license on some devices before activating it on a new one.

Error 5: Activation Failed

This error can occur due to many reasons, such as a network connection issue, a problem with your MacKeeper license, or a bug in the MacKeeper software. If you encounter this error, try the following:

  1. Restart your Mac.
  2. Check your network connection.
  3. Try activating your MacKeeper license again later.
  4. If the error persists, contact MacKeeper support for assistance.

Here are some additional tips for activating MacKeeper:

  • Make sure you’re using a valid MacKeeper activation code.
  • Check your MacKeeper order confirmation email to ensure you have entered the code correctly.
  • Disable any antivirus or firewall software you are running on your Mac.
  • If you’re activating MacKeeper over a proxy network, make sure the proxy settings are configured correctly.
