I have downloaded Tiger A2E Version 2.0 on my computer. However, I understand that under the "Compatibility" tab, I need to choose Windows XP as the "Run this program in compatibility mode for:". My problem is that Windows XP is not on the list. How can I use this software? Or, how do I get Windows XP on the list? When I click on it, the only thing that opens up are 2 screens full of error codes. I would really appreciate your help in resolving this problem.
