Decompressing the LZMA contents does not seem to work with default settings. Here is the LZMA header of setup-0.bin:

tail -c +13 setup-0.bin | lzmainfo
Uncompressed size:             3910839523328 MB (4100812464013508608 bytes)
Dictionary size:               512 MB (2^29 bytes)
Literal context bits (lc):     1
Literal pos bits (lp):         0
Number of pos bits (pb):       3

Uncompressed size is completely wrong, and it is not even the expected 0xFF for when the size is unknown.

Note: the +13 offset before the LZMA header (which is also 13 bytes) was found by trial and error, I don't know what the 13 initial bytes mean yet, maybe some structure defined in the inno setup pascal sources.
