Trying to install product Autocad LT 2009. We had installed this product on another machine that crashed. I get the following error message "The serial number field must contain the serial number in numerical digit format (i.e. 1,2,3)"
Our serial numbers consist of 11 digits, and appear in the following format: 123-45678910. Without posting the number here in the public forum, can you verify if the number that you entered contained any letters or special characters?
Should you need assistance looking up the proper serial number or validating the current one, please feel free to contact our License Assistance Team for direct support.
