Age of Mythology - Windows 10

Still getting just a bunch of error messages. 

When I click download, it asks "what should Firefox do with this file?  Open with....or save file.  Can you give me step-by-step instructions from here?  I'm not sure whether I'm doing it right.

That is right, click "save as" then save it to your computer. After it is saved right mouse on it and choose "extract" when it is extracted, double click the folder to open it, copy the aom.exe and then follow the instructions in the previous post to copy it over the original file.

How do I do this step?

Copy the aom.exe from the downloaded file and replace the one in the game directory.

Follow this link and it should work

Brief Steps

1. In folder "Program Files (x86)\Microsoft Games\Age of Mythology\gfxconfig" - Copy the contents of "geforce3.gfx" to the file i845.gfx using a notepad. Take a backup of the files before you copy.
2. Create a Shortcut of the "aom.exe". In the properties of the shortcut, edit the Target file line, add after the quote "xres=640".

p.s. The quotes should not be used when actually making the edits.

I followed your instructions but it still doesn't work.  I double click the short cut on my desktop and the screen goes black for 2 seconds, then reverts back to the desktop (after I click "allow publisher to make changes")
