IBugTraqProvider: "The issue-tracker provider could not be created. Please check that it is installed correctly."

I've been trying to get an installer working for an IBugTraqProvider application that I wrote for our internal project tracking system. But after I install it and try to configure the provider, I get an error that the provider can not be created and that it might not be installed correctly.

Here's my inno setup script. Can anyone tell me what I am doing wrong? I've verified the GUID in the setup script is the same as the guid in my plugin class.

I am running the installer on Windows 7, 64bit.

#define MyAppName "TortoisePTS"
#define MyAppVersion "1.0"
#define MyAppPublisher "**********"
#define MyAppURL "http://www.*********.com"
#define MyAppID = "{{9C37AA48-FEA5-48E5-A534-A204A169F42D}"
