On: 7-Zip 25.00

[Dwedit]

7-Zip 15.05 is still useful today, because it was the last version to include built-in support for decompiling NSIS installer scripts. The feature was removed due to security concerns.

I've not personally used it, but there's a fork that adds NSIS decompilation back in: https://github.com/myfreeer/7z-build-nsis

Why is decompiling NSIS a security concern?

[Dwedit → parlortricks]

In case of bugs in the decompiler. Extracting the files is still possible in newer versions, just not decompiling the installer scripts.
