Secugen Fingerprint scanner with ASP.NET website

I have been working on implementing the Secugen fingerprint reader and API into a ASP.NET website for a homeless shelter and it is driving me insane. I am using the FDx SDK Pro for Windows API and I have custom COM components (via OCX file) that imports activeX controls into my toolbox. However the controls are only able to be used when I create a Windows Application and then create a windows form. I need to have these controls in a web form. If I try to put them in the webform the activeX tools are grayed out and it doesn't let me. There is an example with the .htm that does exactly what I am looking for so I know it is possible but I just can't tell what the dependencies are. I just am not familiar with .NET and assembly libraries. Here is the readme that comes with the API that contains the different files it has. I'm not sure if I have to create a Windows form first and then put it into my website as an object. I have tried to just put the "SecuGen.FdxSdkPro.Windows.dll" file into my bin folder but then when I run it I get the following error when I go to run it. Any input would be appreciated and let me know if uploading the .htm example or providing code would be any use.

I accidentally have two accounts. The first thing is yes you do have to be sure are installing the SDK on the proper bit server. I ended up taking the active-x controls and embedding them into the web form. Then when the fingerprint was captured and it was converted to a string which was sent via ajax to the server.

I then ran into an issue where the SDK did not have a function to properly de-crypt the string for comparison. I contacted Secugen and they were awesome about getting my request to an engineer which then supplied me with another .dll file which contained the missing functions. One of these days I'll probably post up some source code on GitHub. When I do I'll update this with the link!
