Hello,
Sorry for the late reply, i thought i already replied to your post!
The PDF Creator is an activeX, you can add a reference to the dlls in your application or add the Creator as a visual component on your form.
Also if you want to use it from ASP.Net you can use the PDFCreator.Net, it is a .Net Component.
Please feel free to download our ASP.Net technical note from the Support section in our website

For your specific question, if you integrate the PDF Creator in your application, you will only need to install your application on the client machines.
Hope this helps.
