Zip compatible installer
Can NSIS create a zip compatible installer? A exe that can be opened by WinZip/WinRar as a SFX zip?
I was told there was a plugin that allows it but have had no luck finding one.

No, NSIS does not use the ZIP file format.

Doesn't NSIS use zlib for compression?
If it does, all that would be needed would be a zip header at the start of the compressed data and a footer at the end of the exe.

NSIS uses zlib or bzip2. But I think Justin has optimized zlib, and made it incompatible during the process. I would have to check this out to make sure.

But even if it will be done, it won't be done before NSIS 2 and would only be done if a flag has been set in the script. You should add a feature request at the SF project page for now.

There is no such plug-in that does this. Plug-ins are currently runtime only. This change would have to be made in the compiler.

This feature, if implemented, would cause a lot of internal changes to makensis, which raises the question - why? NSIS builds installers, not SFX.
