Hello @davidbenjaminndundu-collab

That sounds frustrating, it looks like your installation of wamp is incorrect or at least does not have the correct settings or certificates to have a successful ssl connection.

Maybe you can check the installation docs to see what can be changed to fix it.

Step 1: Confirm your PHP path

Open Command Prompt (CMD) and run: php -i | find "Loaded Configuration File"

Make sure it points to the same PHP you’re using in WAMP: C:\wamp64\bin\php\php8.1.0\php.ini

Step 2: Download the latest cacert.pem

Your SSL certificate bundle is outdated, let’s get the latest one.

1. Go to this official source: https://curl.se/ca/cacert.pem

2. Save the file as cacert.pem

3. Place it in: C:\wamp64\bin\php\php8.1.0\extras\ssl\cacert.pem (If the extras\ssl folder doesn’t exist, you can create it.)

Step 3: Configure PHP to use the new certificate

Open your php.ini file (found in the path from step 1), and look for the line: ;curl.cainfo =

Uncomment it and set it to your path: curl.cainfo = "C:\wamp64\bin\php\php8.1.0\extras\ssl\cacert.pem" openssl.cafile = "C:\wamp64\bin\php\php8.1.0\extras\ssl\cacert.pem" Make sure to use backslashes () and the correct PHP version folder.

Step 4: Restart everything

1. Close all CMD/PowerShell windows

2. Restart WAMP (or restart the Apache + PHP services)

3. Open a new CMD window and check: php -r "print_r(openssl_get_cert_locations());" It should show your new cacert.pem path.

Step 5: Re-run Composer installation

Now run the Composer installer again: php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" php composer-setup.php php -r "unlink('composer-setup.php');" If everything is correct, it should install successfully without the SSL error.

Step 6 (Optional): Add Composer to PATH

Move composer.phar to a global location: move composer.phar C:\composer\composer.phar

Then add this to your system PATH: C:\composer\

And test: composer -V
