#261 NSIS file could not be extracted

[Phan Tiến Hưng]

Hello Igor,
I tried to extract file Anaconda2-5.1.0-Windows-x86_64.exe (which seem to be an NSIS file). During extraction, when 7z try to Decode file, it return E_NOTIMPL. Could you please check why this NSIS file couldn't be extracted?
The file can be download at link: https://repo.continuum.io/archive/ , file Anaconda2-5.1.0-Windows-x86_64.exe. Also tested with file Anaconda2-5.2.0-Windows-x86_64.exe and res code E_NOTIMPL returned as well.

Hello Igor,
Update to the ticket: Using nsis 3.03, I manage to generate a file which compression method is kCopy, but this file is extractable using 7zip.
Why there is the different between extraction for these two file that have the same compressiong method?

Attach the file sample file and the nsi script used to generate the sample file.
Thank you.

It's difficult to download that big file to test.
