--- Comment #3 from macintoshman_2001@yahoo.com --- You can work around this with "/extract" as a command line flag to the installer and it will extract to a folder in the same directory as the installer.
http://www.advancedinstaller.com/user-guide/exe-setup-file.html shows additional options like if you want to save to a certain location and not just the random folder name it goes to.
Once extracted you can install from the intall_____.msi in the new folder and it will install fine(including checking the box). This was done in a wineskin wrapper 1.7.23 in OS X.6.8 and OS X.8.5 after it gave me the same inability to click the license checkbox.
