Noone is able to say since they didn't write the code and have no idea what it's doing or using. If your code uses components that at 32-bit, you're going to have problems.

If you want to work with the pdf document at the server side, you simly right click on the project and choose Add Reference. If you want to open a pdf document or play a media file, the client machine needs to have the pdf viewer/media player installed, and you might be able to host it on your web page using the object[^] element.
