Try this;

Find a *.bat file and right click on it.

Next click on "Open With" in the context menu

( if you can not see or select "Open With" in that menu click on "Open" at the top of the menu. A window should pop up with "Windows cannot open this file:" at the bottom there is two options, click on "Select the program from a list" and then click "OK" )

Now a window will open up entitled "Open With" with a list of programs you can select.

At the bottom of this window is a "Browse..." button, click it.

This will bring another window up, use this to navigate to "C:\WINDOWS\system32"

In the system32 folder look for this program "cmd.exe", select it and click "Open".

Now click on "OK" at the bottom of the "Open With" window.

That's it, cmd will run the bat file you selected. Just close it and try running any other the AAA auto installers.
