I am assuming you are talking about the Twine 1 installer.
Some questions:
1. What operating system (brand, version, edition, 32/64bit) are you using?
2. How did you try to open the application?
eg. Did you click on a desk-top icon, did you click on a start-menu menu item, did you try to run the application's executable from within a file manager, etc...
