I have Adobe Acrobat Pro and want to see how a form I created works using Adobe Reader

I had this same problem. Designers who want to be thorough like to know the user's experience. The Adobe Reader installer just quits when it detects the Pro version. There is no option to install both. I ended up uninstalling Acrobat Pro in the Creative Cloud App then downloading and installing Reader. It's a bit cumbersome to do, but luckily I have an iMac and a laptop, so I have Acrobat Pro running on my iMac and Acrobat Reader on my laptop. I am surprised that Adobe, with a target audience of creatives, does not seem to recognize that Reader is a tool that we need to do our work well. 

I'm making the assumption that you have Adobe Reader installed on your system. If not, you have to install the program first then follow the process below:

Provided that you have Adobe Reader installed,  all you have to do is navigate your way to where the final form file is stored, using File Explorer in Windows or a Finder Window on a Mac. Place your cursor over the file and click the right mouse button to open the context-sensitive menu onscreen. For those Mac folks who still have a single mouse button, you can get the same result by holding down the Control key while you click the mouse button.

Choose the Open With command from the flyaway menu, and if Adobe Reader is installed, it should appear among the program options you can then choose onscreen. Choose it and you will open the file just like anyone else who would use Adobe Reader and test the usability of your form.

Hope this helps,

@William376049507edr I would create the form in Acrobat Pro.  Save the PDF in a specific way using Acrobat Pro. When you are finished creating your form, go to File > Save As Other > Reader Extended PDF, and then choose the option "Enable More Tools (includes form fill-in & save)". This process adds the necessary usage rights to the PDF document, allowing users with the free Adobe Reader to fill in the form fields and save their data locally. Without these extended rights, Reader users might encounter limitations or be prompted to sign in to access features that are only fully available in Acrobat Pro.

To test it out, close Acobat Pro's application. Then open Adobe Reader, to test it out.
