I cannot open https://www.uspto.gov/sites/default/files/forms/ProvisionalSB.pdf this pdf, despite installing to the latest Adobe product. I am working on a MacBook Prop 15-inch, 2.53GHz, Mid 2009. Processor 2.53 GHz Intel Core 2 Duo. Memory 4 GB 1067 MHz DDR3. Graphics NVIDIA GeForce 9400M 256 MB. OS X Yosemite.
do you have a subscription for acrobat? that would cost money and show here, https://accounts.adobe.com
or are you using the free adobe reader?
or by "..latest adobe product" you mean something else?
attaching a screenshot of whatever your think would open a pdf, that's installed on your computer, would be helpful.
Moving this discussion to the Acrobat General Troubleshooting forum.
I can open it just fine, and I'm not in the US, either.
What happens when you try to open it? What do you see? Use the Camera icon to post a screenshot (do not do it via email!), please.
Make sure you're saving the file locally and then opening it in Adobe Acrobat/Adobe Reader. This is an LCD form and most other PDF viewers can't handle it.
