Seem like browser compatibility issue,

Try enforce compatibilty using meta tag

X-UA-Compatible

or try another browser or upgrade browser if you use older browser

Hi [e-mail],

According to your description, you say it works in one computer, but it doesn't work in the other computer. i think code should work, maybe this issue caused by the client environment. I suggest you could test it with other browser in not work computer. 

Also if you meet any error or exception when you execute the code? 

Also you could refer to this tutorial:
