Tach Andreas,
> the ff library?
yes
thank you very much, this hint saved my live.
For any other, here the magic sentence:
"If you specified a password for use of your digital certificate when you bought it, then you must install the associated private key in your Windows system local stores. This way, you only enter the password once, when you install it."
Found in:
"Adobe Font Development Kit for OpenType - Beginner's Guide to Digitally Signing OpenType Fonts"
thanx again
