Windows 7 - Installing fonts in Windows 7

Hello
I want to install some "old" fonts (TTF and Adobe PS) on Windows 7
I tried to copy them in the c:\Windows\Fonts directory, but copy is refused

I also had a message telling that I have not the rights to do that

I bought a configuted computer with Windows 7 - 64 bits already installed and defined myself as an administrator, but this problem sometimes happen (for instance with Xplorer2)

How could I solve this (these) problems ?

Thanks
