Hi Chris,
Thank you for posting your query on Microsoft community.
I understand that you are unable to use nitro PDF creator in mail app. This will happen when you don’t select the default application as nitro pdf creator.
Follow the steps to select PDF nitro as default application.
- Open search windows (windows key + S).
- Search for default program.
- Select set your default program.
- Select the (program) Nitro PDF creator.
- Select option set this program as default and then click on OK
Check the link below to select a default application.

If this doesn’t help I would suggest you to uninstall and reinstall Nitro PDF Creator
For second issue: I would like you to inform that in Mail application there is no option to print the selected pages in a multi-page document.
Hope this will help you.
Please get back to us if you need any further assistance, we will be glad to help you.
