WAMP Server errors switching Apache / PHP versions on fresh install

Question

A fresh download and install of WAMP Server works successfully (Apache 2.4.4 PHP 5.4.12).

However as soon as I install a different version of Apache, in this case 2.4 to 2.0 (so I can run PHP 5.2 & 5.4), WAMP goes offline with an orange icon.

If I try to switch BACK to the original Apache version I get this show-stopping error:

Sorry,

This Apache version doesn't seem to be compatible with your actual PHP Version.
Switch cancelled.
Press ENTER to continue...

This doesn't make any sense, as this is a fresh install so both the Apache + PHP versions are the defaults.

Here's what the UI is telling me:

• The WAMP icon is now orange
• the Apache/Version/2.4.4 icon has a red warning icon next to it

• the Apache/Version/2.0.63 icon has a tick next to it

  

I've tried installing other versions of Apache too, but the issue seems to be with the base 2.4 WAMP installed options.

Extra info: port 80 is free, and I used to use WS 2.0e all the time without these kinds of issues.

Thanks, Dave

Go To \wamp\bin\php\phpX.Y.Z\wampmanager.conf.

Edit wampmanager.conf via Notepad++

Add This Codes.. And Save wampmanager.conf

$phpConf['apache']['2.4']['LoadModuleName'] = 'php5_module';
$phpConf['apache']['2.4']['LoadModuleFile'] = 'php5apache2_4.dll';
$phpConf['apache']['2.4']['AddModule'] =  '';

Restart Wamp Manager..
