I know this is an old post, but in case someone arrives here, this might help them out as it just did for me as I migrate an old project onto a new PC.
A clean install of Windows 10 Enterprise (or maybe even Home edition) does not have all the Arial font variations. Microsoft Office installs the additional ones like Arial Narrow. So, if you have the font on an existing computer, copy it from the C:\Windows\Fonts folder and when you install on the new computer, be sure to right click (or highlight multiple fonts and right click) and select "Install for all users". Don't just drag and drop the font files into the folder.
Thanks to Anton for pointing this out.
