Well, I can only say that I must be REALLY stupid!
How the heck do you get started with 1password? How do you install? I downloaded the trial version and unzipped it - now what? there's no exe file that I can see to install it. Nor can I see the answer in the tutorials!
Because if I go to the [url="http://agilewebsolutions.com/downloads/1Password/Windows"]Download page[/url], it automatically downloads the 1P installation .exe file.
Pazzle is correct, it sounds like you downloaded the Mac version which is a zip file that extracted into a .dmg file. The Windows version will be downloaded as [a file with] an .exe extension.
