The differnce between Quicktax Platinum and Standard?

I thought it was all about QT platinum including QT tracker and retirement planner etc. But the difference is far more simple: The second last digit in the Installation is 2 for Platinum; 0 for standard. Choose whichever version you want. But make sure the checksum of the last two digits stays the same

whoa. you mean the intallation key code?

So to convert a standard QT to a platinum QT is to change the 0 to a 2?

btw, what do you mean about the checksum of the last two digists staying the same. What is a checksum???
