Netbeans doesn't see newly installed fonts [duplicate] - netbeans

Question

I am trying to add new fonts to my Netbeans editor by downloading them and double-clicking the .ttf files and pressing 'Install' on the upper left corner. I am able to install the fonts with no issues. However, when I reload Netbeans and go to select the new font, it does not appear on the list of available fonts. Restarting Windows doesn't help. Has anyone had this issue before? And if so, we you able to fix it and how?
Thanks in advance.
EDIT: I am using Netbeans 10.
EDIT2: I am trying to install Roboto Mono and Inconsolata, here are the links to the downloads:
https://fonts.google.com/specimen/Inconsolata
https://fonts.google.com/specimen/Roboto+Mono
Get back to me if you have any luck, thank you.

Answer 1

Initially I had the same problem as you. After installing the new fonts and rebooting, those new fonts were not available in NetBeans 10.0, even though they were available in other applications such as Firefox and Notepad.
In my case, installing the *.ttf files resulted in them being installed in a user specific folder: C:\Users\johndoe\AppData\Local\Microsoft\Windows\Fonts.
However, after I copied (only) the *.ttf files for Inconsolata from that folder to C:\Windows\Fonts and rebooted again, the Inconsolata font was visible in NetBeans 10.0. Here is a screen shot showing the use of Inconsolata font:
Notes:
I don't know why this action was necessary. I'm pretty sure I have installed other fonts for NetBeans in the past that didn't require manually copying them to C:\Windows\Fonts.
This issue isn't specific to NetBeans 10.0 for those particular fonts; it also exists in NetBeans 8.2.
Don't use Windows File Explorer for copying the fonts since it treats C:\Windows\Fonts in a special way. Instead, copy the *.ttf files to C:\Windows\Fonts using copy from the command line:
I'm not sure whether this is a NetBeans issue or a Windows 10 issue, but since other software picked up the new fonts from the user directory perhaps this is a NetBeans bug?

Answer 2

As mentioned in previous answers, NetBeans only shows up fonts that are installed globally (for all users).
If you just use „install“ from the context menu in Explorer or from the font preview window, the font is installed on a per-user basis and is not installed globally.
You don’t have to move the font files manually. There's a clean way to do this: Use Explorer to navigate to the folder where your TTF files are stored. Then right click on a ttf file and choose "Install for all users".

Answer 3

Run command cd "c:\Windows\Fonts"
Force delete all fira fonts del f/ firacode-regular.ttf
(in my case, I had this font installed before, which is the one I want to use, so I will have to remove it to continue with the explanation)
Copy .ttf font file copy "c:\users\mrconejO07\desktop\firacode-regular.ttf" "c:\windows\fonts"
(in my case these are the paths where my file is and where it must be copied)
In theory it should work in the NetBeans IDE, enter to verify that the font should already appear in the options menu and if you see strange symbols when selecting the font you should ...
Open the .ttf file of the font you want to install and install it, now if it should work correctly.
