My understanding was that DPS would be hosting the payment page for us. Why do i need to install the COM object?
For windows systems the COM object is required to handle the 3DES encryption in the URL string given to our Host and the response given back, which the COM has to decrypt from the response string. It has built in method calls and exception handling, so there is less programming for the merchant to do. If you cannot install any COMs on your host for any reason, you would need to use our platform independent products like PX Post with your own SSL certificate. Exception handling would need to be written by yourselves as well.
