Upgrading to MAMP 3: “The installation cannot be continued!”

Question

I’m trying to upgrade my current MAMP installation to the latest version (3.0.7.3). I have quit the current version and tried to run the installation package.

Each time, the installation have failed: “The installation cannot be continued!”

And I’m served with the following instruction: “Please quit MAMP / MAMP PRO as well as all servers and deactivate the Dynamic DNS Services before you restart the installation process.”

I’ve tried to run the installation while connected to the internet and not connected, to no avail. I don’t quite know what this Dynamic DNS Service is about.

Any advice or suggestion to troubleshoot this issue?

Many thanks,

P.

Answer 1

In my case, I needed to kill all mysqld and httpd processes before it would install. Open terminal and run the following commands:

sudo killall mysqld
sudo killall httpd

Answer 2

I encountered the same issue. The solution was to stop the default mysql server which is included in OS X:

Open Application -> Utilities -> Activity Monitor

Search for mysqld in the process list and stop it. The MAMP PRO installation will work now.

Answer 3

I started mamp again after the install failed and found that apache was still marked as running. I stopped apache through the mamp interface, closed mamp, and then ran the installer again and it worked.
