It isn't clear to me if you are trying to load fonts permanently for use by all programs, or temporarily, and why it would be a problem for temporary fonts to be available only to Adobe programs, or perhaps you mean the fonts SHOULD only be available to Adobe programs (in which case you would put them in C:\Program Files\Common Files\Adobe\Fonts on 32-bit Windows, or C:\Program Files(x86)\Common Files\Adobe\Fonts on 64-bit). There is also a fonts folder in the ID application folder that is accessible only to InDesign.
For CS5 and later, you can also create a folder named Document Fonts in the same directory as the .indd file and fonts placed in that folder can be used by that .indd file for editing.
thanks for your answer. Than i will explain it a little more.
The Fonts we are copying into (C:\Users\<Username>\AppData\Roaming\Adobe\Fonts) are showing up and are usable in all Adobe products exept InDesign. The other Folders like system, programm files we can´t use because there are protected by the system and only writeable with admin rights. We only work with Adobe products so we only need the fonts in these programms. We have vor each User (projects) seperate font packages. So the only thing is why dosen´t find InDesign these fonts in (C:\Users\<Username>\AppData\Roaming\Adobe\Fonts).
Have you tried the two locations I mentioned in my first post? They also appear to be restricted, but it looks to me like an Admin user can change the permissions to allow ordinary users to write to the Common Files\Adobe\Fonts folder.
Yes i have tried. The locations are protected like you sayed. But here is the problem when the admin give write access the fonts in this folder are global for all users and that is what we wouldn´t have. We would have the fonts only for the current user because an other user need other fonts which could collide with other.
I don´t understand why all adobe programs (Photoshop, Illustrator) use these fonts (folder) exept InDesign. That isn´t normal.
Presumably only one user is logged in at a time on each machine. The user could add and remove their fonts as required.
