Payflow Pro COM object error

[doron23]

I'm using payflow pro but am getting an error when processing orders:

PHP Fatal error: Uncaught exception 'com_exception' with message 'Failed to create COM object `PFProCOMControl.PFProCOMControl.1': Invalid syntax
' in C:\Inetpub\wwwroot\zencart\includes\modules\payment\payflowpro.php:357

The instructions I'm seeing in the various forums are that I need to install the SDK since I'm running on Windows (Windows Server 2003, IIS, PHP 5.2.5).

Going to the PayPal Manager I'm seeing the following available downloads:

.NET SDK for Payflow Pro
Java SDK for Payflow Pro
HTTPS interface (PDF)

I tried installing the .NET one but I'm getting the same error and I admit I'm kind of confused about what to do next. Anyone else run into this issue and knows what needs to be done to get transactions to work from here?

Why not try the new one in the downloads area ... that doens't have the COM dependency?
