// * the installer is composed of the following parts:
// exehead (~34kb)
// firstheader (struct firstheader)
// * headers (compressed together):
//   header (struct header - contains pointers to all blocks)
//     pages (struct page)
//     section headers (struct section)
//     entries/instructions (struct entry)
//     strings (null seperated)
//     language tables (language id, dialog offset, language strings)
//     colors (struct color)
// data block (compressed files and uninstaller data)
// CRC (optional - 4 bytes)
//
// headers + datablock is at least 512 bytes if CRC enabled

nsis dont store the compress method - they simply used the stub.exe with included compressing algorithm. total 6 stubs lzma/bzip/lzw + _solid version.
to detect the compression algorutm you need binary compare files from C:\Program Files (x86)\NSIS\Stubs\ and yours exe, the first 34 kb should be match at 98%


lang_table - the array offsets for string table. if you need e

lang_table[x]  = offeset in
