Hi,

We are proud to announce the second preview of Inno Setup 7, which includes a 64-bit edition, as well as a 32-bit edition.

Both editions of Inno Setup 7 can build either 32-bit or 64-bit installers, and they can be installed side by side, and they can coexist alongside Inno Setup 6.

Additionally, support for extended-length paths was added, removing MAX_PATH limitations.

Great care has been taken to ensure maximum backward compatibility with Inno Setup 6, including backward compatibility for the extended-length path support, and compatibility between 32-bit and 64-bit installers.

For the complete list of changes, see What's new in this version?

Download 64-bit edition
Download 32-bit edition

Using the 64-bit edition is recommended. As noted above, it can still build 32-bit installers.

Please test your scripts and installers with this preview, even if you do not intend to use 64-bit installers, and report success or failure by sending a quick email to inno...@googlegroups.com (preferred) or ml...@innosetup.nl. Thank you in advance. Especially please test and report this functionality:
  • Using 64-bit install mode in a 32-bit installer.
    This is not new functionality but we did many changes related to system path redirection.
  • Using 32-bit install mode in a 64-bit installer.
  • Using Pascal Scripting in a 64-bit installer.
    Please do first ensure your script is actually compatible with 64-bit execution. What's new has some tips about this.
Please do not use this preview to build installers you will use in production.

If you installed the 32-bit edition of preview-1, please uninstall it yourself before installing preview-2, because its AppId has changed. See GitHub for a comparison between preview-2 and preview-1.

Greetings,
Martijn Laan and Jordan Russell
