When the following URL is not available, what other timestamp URL can I use in my setup authoring tool? The specific error I get is: SignTool Error: The specified time
SignTool Error: The specified time
Honestly, I would just try again. But you can use any of the following:
http://timestamp.globalsign.com/scripts/timstamp.dll
http://timestamp.comodoca.com/authenticode
http://www.startssl.com/timestamp
