Hello,
It could be that the font was installed in user context.
When you install a font in windows by using the context menu on font file (or from the font application), it will install the font for the current user only (even if you run elevated). This means that the physical font file is stored in
"C:\\Users\\USERNAME\\AppData\\Local\\Microsoft\\Windows\\Fonts\\xxxx.TTF"
and the registry information is in
[HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Fonts]
This means that the font cannot be found by the service that runs on a different account.
Solution:
Install the font in the system using a power shell script or any other system application that can install the font in c:\Windows\Fonts and place the registry data in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts
Hope this does help.
