To support our development efforts, we request that all commercial users of Inno Setup purchase licenses![[external link]](images/extlink.png)
, regardless of the version being used.
Thank you for helping ensure the continued development of this software.
After purchase, you will receive your license key via email. If you do not receive your key in your inbox, please check your spam or junk folder. The sender address is innosetup@mlsoft.nl. Please make sure it is not blocked by your email system.
Once you have received your key, copy and paste it into the 'Enter Commercial License Key' dialog in the Inno Setup Compiler IDE, which can be opened from the 'Help' menu.
Your license key can also be activated for a user by writing it as a single line to the following registry key:
- Key: HKEY_CURRENT_USER\Software\Jordan Russell\Inno Setup\License
- Name: LicenseKey
- Type: REG_SZ
You can do this before or after installation, or even while Inno Setup is running.
A license key is a string of at least 108 characters. It always starts with 'in' and ends with 'no', without the quotes. To users the key is presented as multiple lines of 28 characters per line.
Please note that installers built without a license are not explicitly marked as unlicensed. This means you may choose not to install the license key on a CI machine, even if we ask you to assign a license to it.
