If you manage to install Worldspan (GO RES) on your computer and the program still doesn’t work, you get error messages like invalid path or missing Active X, you can make some changes that will make your program to work.
Open Internet Explorer.
Go to Tools > Internet options.
Depending on your Internet Explorer version, you might have a settings wheel instead of “tools”.
From Internet options, go to security, and click on a custom level.
Right there, enable pretty much everything where is saying “Active X”. Also enable everything from .net control.
Restart Internet Explorer.
Worldspan (GO RES) should now work with no other issues.
Be careful, do not use Internet Explorer for anything else except Worldspan. Use instead Mozilla Firefox or Chrome.
