It is possible that the file extension ".exe" was somehow lost from the Propel Accelerator installation file. You can easily check and, if necessary, remedy this situation. Here's how:

First, find the installation file you downloaded. Unless you changed the name during the installation process, search for "propelsetup". Use the Window's Start menu: Start -> Search -> For Files and Folders...

When you find the file, select it. The full name of the file should be visible.

If the ".exe" extension (without quotation marks) is missing, add it. Click on the filename and add the extension ".exe"

You should be able to double-click on the file right in the Search Results window to start the install.
