Go to your Program FilesInstallShield Installation Information and find the folder that has the MOHAA info...when you open the folder you will have a series of folders with cd-key looking numbers...open each folder and you will see a setup.ini (looks like a notepad with the gears)...open it and look at the "AppName=" line. Look for the folder with the one that has the line "AppName=MOHAA" and delete the whole folder. Once you do that, it should let you reinstall.
