Hi Katie,
I don't get the error, a message box does pop up if the installer finds a previous version.
How about rather than using a force to use the /x and uninstall first?
It wouldn't have anything to do with this line in your XML would it?
ProductCode="Crystal.Reports.Special.3.0.11"
Shouldn't that be :
ProductCode="Crystal.Reports.Special.13.0.11"
Thanks again
Don
