License settings should be set before building a protected EXE. These settings are compiled into the EXE at build time.

Keygen Password
If you leave the password field blank, Thinstall will disable the License System Version 2 for your EXE.
The password you use when building your software should be the same as the one you use to generate license keys later. There is no password recovery, so make sure you write down your password. If you lose the password, or use the wrong password when generating a license key the key will not work with released versions of your software.
By changing the password field from release of Version 1.0 and Version 2.0 of your software, you prevent old 1.0 license keys from working with Version 2.0 of your software.
By keeping the password field the same from release of Version 1.0 and Version 2.0 of your software, you allow 1.0 license keys to be used interchangable with 2.0 .
Display register dialog on start (when condition(s) below applies)
When this option is selected, Thinstall will display the register dialog box before the program starts if the current license key meets one or more of the conditions below.
Display register dialog on quit (when condition(s) below applies)
When this option is selected, Thinstall will display the register dialog box when the program quits if the current license key meets one or more of the conditions below.
If the "display on quit" is selected but not "display on start", the use will not be prevented from using the software when the license expires. In this case the end dialog functions as a "nag" screeen.
Display Machine ID on register dialog (when condition(s) below applies)
When this option is selected, the user's Machine ID will be displayed on the Key-entry dialog box. If you do not plan to issue keys that are locked to the Machine-ID, then you should uncheck this box to avoid confusing the user.
Display register dialog when a key's 'runs left' has X of fewer runs remaining
When this box is checked, Thinstall will display the register dialog box if the current license key (default key if none entered by the user) has a limited number of runs allowed and the number of runs remaining is less than X. If the current license key does not have a restriction on the number of runs allowed, then this condition will be ignored.
Note: If neither 'display on start' nor 'display on quit' are checked, the register dialog box is never displayed.
Display register dialog when a key's 'days left' has X of fewer days remaining
When this box is checked, Thinstall will display the register dialog box if the current license key (default key if none entered by the user) has a limited number of days allowed and the number of days remaining is less than X. If the current license key does not have a restriction on the number of days allowed, then this condition will be ignored.
Note: If neither 'display on start' nor 'display on quit' are checked, the register dialog box is never displayed.
Display register dialog when a key's 'expiration date' expires in X or fewer days
When this box is checked, Thinstall will display the register dialog box if the current license key (default key if none entered by the user) expires on a specific date and the number of days until that date is less than X. If the current license key does not expire on a specific date, then this condition will be ignored.
Note: If neither 'display on start' nor 'display on quit' are checked, the register dialog box is never displayed.
