The file you are trying to open is 61495 x 5329 pixels. There are not a lot of viewers that are going to handle that gracefully.
I was able to open it in Preview on my MacBookPro from a bunch of years ago. Zooming worked nicely.
Other things to try would be Photoshop or a good GIS viewer. QGIS will probably work since it is designed to display large raster images like this.
