COM on NT

I am trying to invoke COM on NT using the following line of code $outl = new COM("Outlook.Application") or die("Unable to instantiate Outlook"); and I get a DR.Watson alert for php.exe shows an "access violation". This is my first attempt to exercise COM on this site, so it could be something like a missing dll, or extension. What should I look for? should I precede this with a dl("php_xxxx.dll") to load an extension, if so which one? thanks in advance, Warren Vail Tools, Metrics & Quality Processes (415) 667-7814 Pager (877) 774-9891 215 Fremont 02-658 warren.vail@schwab.com <mailto:warren.vail@schwab.com> Warning: All e-mail sent to or from this address will be received or otherwise recorded by the Charles Schwab corporate e-mail system and is subject to archival, monitoring or review by, and/or disclosure to, someone other than the recipient.
