Deploying files?

I have a really simple program that all it does is opens a fillable PDF file and populates data from an XML file and then when the user is done they can click a button on my main application and have it go back through all of the fields on the form and save the data back out to the XML file so it can be called up later with their changes. I'm not saving the form itself, just the data in it. I am using C# as a language and I can get everything to work great on my machine using AFORMAUTLib and Acrobat.dll. I have a test machine set up with Acrobat 8 Reader (which all of our clients will have) but I don't know how to deploy it. I've copied all of the files I used (Acrobat.dll and the interops that C# creates) but it crashes saying it can't load the library every time. The error is due to the Acrobat.dll. I don't have a problem paying for licenses to distribute this to our clients but it seems crazy that they would all need to have Acrobat 8.0 Professional since I'm not saving the form or modifying the form in any way. So are there other utilities I can use to do this or what files do I need in order to distribute this? Thank you.
