Every release build since the packaging pipeline landed has failed at "Compile the installer", which is why the last eight versions are still unpublished drafts:
Error on line 63 in msime_setup.iss: Couldn't open include file
"c:\program files (x86)\inno setup 6\Languages\ChineseSimplified.isl"
install-inno-language.ps1 derived the destination from `Get-Command ISCC.exe`. On the windows-2025 image Inno Setup comes from Chocolatey, so that resolves to the shim at C:\ProgramData\Chocolatey\bin\ISCC.exe and the file was written to C:\ProgramData\Chocolatey\bin\Languages\. ISPP resolves compiler: against the real installation. The step printed "Installed ... (21516 bytes)" and exited 0, and the build failed two steps later pointing at a path nothing had written to, which is why this survived eight releases.
The installation is now located by a file only it has -- ISPPBuiltins.iss or Default.isl, neither of which sits beside a shim -- checking the uninstall registry key, the two Program Files locations and any ISCC.exe on PATH, and failing with the list it tried rather than falling back to a guess.
ci.yml now compiles a throwaway script whose only content is a [Languages] entry pointing at compiler:Languages\ChineseSimplified.isl. Asserting the file exists at a path this script computed would only restate the script's own belief; compiling is what proves ISCC agrees. The URL and digest pin moved into the script so that check does not need a second copy of them.
