Brief description of tool

InnoSetup 6.4.0 was available on Windows 2022 image. Since it's not on Windows 2025 build, we have to add a powershell task to all our pipelines to install it using Chocolatey.

Hi @KeithAmt , Unfortunately, at the moment we are trying to make the images as light as possible and trying to avoid installing programs and packages that can be easily and quickly added at runtime. Thank you. Closing this issue.

This is an unfortunate decision. The number of requests to add InnoSetup to the windows-2025 image clearly shows that. It's OK to change your mind. And this is one instance where you should. All of my Windows CI uses Inno.

Definitly worth adding.
