i have adobe acrobat pro DC and i need to use Nimbus Sans font to edit a file, how to proceed?

I'm not convinced that a subscription to Acrobat DC includes access to fonts, as that is not normally needed. You can check that, however, by going to fonts.adobe.com (https://fonts.adobe.com/fonts/nimbus-sans), sign in if you aren't, and search for the font you need. If you can install, install.

If you can't install, it's probably not included (you can confirm this by contacting Adobe customer care). You would need to buy the font from the foundry URW.

Adobe customer care can be contacted by beginning a secure chat session at https://helpx.adobe.com/contact.html?rghtup=autoOpen. If the chat window fails to open, or is non-responsive, use a different device to start the interaction.
