Failed to create COM object 'X': Class not registered in another WAMP

Question

There already is a working WAMP instance in a Windows 7 in which the line

$x = new COM("X");

does instantiate a COM object.

I was trying to locate a bug, and decided to use a fresh new WAMP installation on the same Windows 7 system as the previous one.

In the new one, the same line produces:

Failed to create COM object 'X': Class not registered ( Error code: 0x80040154 )

Now, since the first WAMP comes with it's own installation application (along with its DLL which holds the COM class) I can't exactly figure out what I need to change in the new WAMP so the line above will instantiate the object.

My WAMP version is: 2.2 and
Apache version : 2.2.21
PHP version : 5.3.10

Any idea what I need to set up properly?

You need to register the DLL, using

regsvr32 yourdll.dll

Exactly why I said that "There already is a working WAMP instance in a Windows 7 in which the line $x = new COM("X"); does instantiate a COM object." so that means, the DLL is already registered, right? – Azder Nov 19 '12 at 15:12

Oh, these are on the same machine? – Simon Richter Nov 19 '12 at 16:15
Yes, they are on the same machine. – Azder Nov 19 '12 at 17:33

Managed to solve the problem by changing the working directory (using chdir) to be the same as the php.exe just before $x = new COM("X");.

I think the DLL wasn't propery registered, or lacked something in itself.
