I plan to apply the following patch to fix the issue.
Description: Make NSIS embedded inflate function compatible with zlib
The NSIS implementation of deflate deviates from the original one that
it omits 2 bytes (NLEN - the one's complement of the number of data
bytes in the block) in the header of each non-compressed block (BTYPE=00).
[For details see section 3.2.4 in RFC 1951].
