This is somewhat related to my previous question, Why do installed fonts disappear after reboot?.
Having got the font install issue sorted out under XP just fine, recently we've got a Windows 7 workstation and I've created a special GPO for it. Initially it was UAC that was demanding administrative access to C:\windows\fonts despite the fact the policy dictates that directory is writable (as is the relevant registry entries, on XP anyway). The issue now though is that when I try to copy a font or hit install it claims that the font "does not appear to be a valid font". This happens with every type of font as well.
Is there some new and special consideration when allowing these changes on Windows 7?
Any input would be appreciated.
Many thanks, Doug
