I just tried it and it worked okay for me. The hyperlink I created in Word was to a jpg on my own computer and it opened it fine using my default photo viewer Irfanview. Maybe it is a bug with the photos app you have? Or is the jpg location not on your computer? Maybe you are linking to an online jpg?

Try installing or using another photo viewer as your default to see if that fixes it. Irfanview is free and highly rated by those who test these things (and it works for me) but there are others as well.

I'm using the Microsoft Photos app. The jpgs are on my hard drive. I can double click them and they open in the Microsoft Photos app. The Word document is on my computer and I can link the jpg in Word successfully (as well as all the other hyperlinks). I'm using the Word app, and not the cloud app.

No, I am not linking to anything online.

The Microsoft Photo app is almost certainly not the problem.

All the files are local to my hard drive.

I can open the jpg in a browser just fine.

I can open the jpg in Microsoft Photos just fine.

???

Thanks!

I went back to an old file where I did this. I know I was able to open a .jpg with a hyperlink from Word then. It does not work now.

I tried the wsreset.exe believing it did not apply to my problem. It had no affect.

And just to be sure, I disabled my virus checker. No change.

I still don't see a solution.
