A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .ASPX file, you may have a problem with it because of its version.

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
