can't run premiere tryout

I downloaded the tryout for premiere and tried to install it. When I click on the setup icon with a picture of a window (which is usually the install folder) it loads for a while and does nothing. A lot of the files are on a .DLL extension, so when i click on it it says it doesn't know how to run the program and asks to select it from a list. (It's a windows, if that helps.) Does anyone have a solution?

edit: twenty minutes after all of the seemingly pointless loading, it says about five times that it can't run a 16-bit windows program.
