ANN: Inno Setup 6.5.1 released

[Martijn Laan]

Hi everyone,

Inno Setup 6.5.1 has been released. This update fixes an issue with command-line compilation when using the Compiler IDE and also includes an improvement to the download functionality.

As a friendly reminder, if you or your organization benefit from using Inno Setup in a commercial context, we now kindly ask that you purchase a license. The order page includes an explanation why commercial licenses are now being offered, along with additional information.

Thank you to everyone who has already purchased a license! Your support is vital to our ongoing development.

For the complete list of what's new/changed, see: What's new in this version?.

In case you missed the announcement of 6.5.0 and its highlights, please see below.

Inno Setup remains open source and free for non-commercial use. If you have donated in the last two years, you qualify for a free single user license, regardless of the donated amount. Please see this Q&A. Thank you very much for your support.

Greetings,

Martijn Laan & Jordan Russell

Inno Setup 6.5.0 highlights:

• Introducing commercial licenses If you or your organization benefit from using Inno Setup in a commercial context, we kindly ask that you purchase a license. Thank you for helping ensure the continued development of this software. Licenses can be purchased from our new order page, which includes more questions and answers. All commercial licenses are perpetual and require a single payment. They include two years of updates, major and minor. After this period, your current version will remain licensed and functional as-is.
  
  
• Improved archive extraction It's now possible to extract password-protected archives, multi-volume archives, and multiple extra archive formats such as .zip. Additionally, the [Files] section now supports archive extraction. Writing Pascal Script to extract an archive is no longer necessary. All of this is optional and does not increase the size of Setup if not used.
  
  
• Improved file downloads The [Files] section now supports file downloads. Writing Pascal Script to download a file is no longer necessary. Archives can be downloaded and extracted using a single [Files] section entry.
  
  
• New signature-verification capability Inno Setup now includes an integrated signature-verification capability that can be used to detect corruption or tampering in your files at compile time, before files are included in an installer being built, or during installation, before Setup copies external files onto a user's system. There is no cost involved. Note, however, that these signatures cannot be used to eliminate an "Unknown publisher" warning message shown by Windows when an installer or other EXE file is started.
  
  
• And many more improvements, such as support for encryption of the entire installation and full dark mode support for the Compiler IDE, and improved support for high-contrast themes and screen readers.

Hello Martijn,

 

I have purchased a license a couple of days ago.

Unfortunately, the invoice does not contain all the information needed to make our fiscal authorities happy.

At least we need the full company name including address as the recipient:

 

KeepTool GmbH

Kurfürstendamm 30

10719 Berlin

 

Can you please send me an updated document?

Thank you.

 

Regards,

Holger

Hi Holger,

I will answer this privately as this is not the right place.

If anyone is wondering anyway: invoices list the information you enter at checkout, and can be updated one-time after ordering as explained on the order page in the buyer support topic.

Greetings,

Martijn
