Fatal Error: "Class not registered" creating COM object

Where can I find all of the COM objects that can be created in Powershell?

I'm currently migrating a PHP website from a server running Windows Server 2003 and PHP 5.2 to one running Windows Server 2012 R2 and PHP 5.6.35. One script is giving me a "Class Not Registered" error when creating a COM object:

$obj = new COM('DllName.ClassName') or die ("Unable to create COM object");

I've checked the above questions, and can confirm that:

• The COM DLL is registered on the server (both by checking the registry and using PowerShell)
• The installation of PHP is 32-bit (PHP_INT_SIZE is 4).

I think the next thing for me to look at is the "Advanced Settings" dialog mentioned in the answer to the first question above, but where do I find it? The actual server in use is Apache, installed as part of WAMP, but I think the problem is at a lower level.

The fix was to use the registry hack described in the blog post linked from the first linked question. The full process is:

1. Copy the ActiveX DLL to C:\Windows\SysWOW64 (not System32).
2. Open a command prompt, and register the DLL: C:\Windows\SysWOW64>regsvr32 <DllName>
3. Open the registry (type regedit at the command prompt), and search for the DLL name in HKEY_CLASSES_ROOT\WOW6432Node\CLSID. The DLL should be found in a key named HKEY_CLASSES_ROOT\WOW6432Node\CLSID\{GUID} . Copy the GUID to the clipboard.
4. Create a new String value named AppID in this key (not in any of its sub-keys). Set the AppID value to the GUID (including braces).
5. Create a new key: HKEY_CLASSES_ROOT\WOW6432Node\AppID\{GUID} .
6. In this new key, create a String value named DllSurrogate . Leave the value blank.

The ActiveX object should now be creatable from PHP using the COM functions.
