From what it seems, your version of the application is not compatible with Windows 7. I suggest you delete the installation package and download and install the latest version of the software from the official web page. Click the Download button next to TINKER Executables for 64-bit or for 32-bit Windows, save the file to your computer and install it following the provided instructions. Since the package is large, I suggest you use a download manager from the Software Informer database in order to accelerate the download process.
