According to both SDC and Impulse, I currently have version 3.99 installed. The history section on SDC states there is a new user Interface involved but I'm still seeing the old interface. In the Help - About section of IP, it states I have 3.00 and in the Help - History section, the last build mentioned is 3.20. I've tried using both the Iconpackager.exe and Iconpackager64.exe but both give me the same interface. My OS is Vista Ultimate 64.
