Version Comparison Failed

[Furrypizza]

So I have downloaded Fiesta Online and it's now on my desktop.
When I click on it the InstallShield Wizard comes up and starts
to download/load. At about 95% of the way finished, and error
comes up and says "The version comparison failed. The setup
will now terminate." It then closes out and doesn't finish, therefore
I cannot play the game.


What should I do to fix this?



EDIT: I have uninstalled the game and re-installed it. Still does the
same thing.
