Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
What software on your computer are you trying to set up a signature in, please?
(You can request a Live Phone Call, for an extra payment, if you like. Meanwhile I will try to help you with a text interface in this mode.)
(I regret that I am not able to offer Live Phone Call service at this time; However, your request is still open to other Experts in this category, and one of them may pick up on it at any time.)
