"Air Setup Setup Data" modification: unable to extract

[PatrykMis]

This is modified Inno Setup, probably v5.20.

Firstly, Tried latest GIT version:

>innoextract --debug -i "setup-hyp.exe"
found loader header resource at 0x18eac
found loader header magic version 5.1.5
loaded offsets:
- exe: @ 0xdee8d7  uncompressed: 1.58 MiB  checksum: CRC32 0xde5f5065
- header offset: 0xdc6d58
- data offset: 0x19800

unknown version: "AiR Setup Setup Data (5.2.0)"
Could not determine setup data version!

So tried to dump headers:

>innoextract --debug --dump-headers "setup-hyp.exe"
found loader header resource at 0x18eac
found loader header magic version 5.1.5
loaded offsets:
- exe: @ 0xdee8d7  uncompressed: 1.58 MiB  checksum: CRC32 0xde5f5065
- header offset: 0xdc6d58
- data offset: 0x19800

unknown version: "AiR Setup Setup Data (5.2.0)"
Not a supported Inno Setup installer!
Done with 1 error.

Ok, so added the following line to /src/setup/version.cpp:

{ "AiR Setup Setup Data (5.2.0)", INNO_VERSION_EXT(5, 2, 0, 0), 0 },

Recompiled and tried again:

>innoextract --debug -i "setup-hyp.exe"
found loader header resource at 0x18eac
found loader header magic version 5.1.5
loaded offsets:
- exe: @ 0xdee8d7  uncompressed: 1.58 MiB  checksum: CRC32 0xde5f5065
- header offset: 0xdc6d58
- data offset: 0x19800

At least both headers can be dumped:

>innoextract --debug --dump-headers "setup-hyp.exe"
found loader header resource at 0x18eac
found loader header magic version 5.1.5
loaded offsets:
- exe: @ 0xdee8d7  uncompressed: 1.58 MiB  checksum: CRC32 0xde5f5065
- header offset: 0xdc6d58
- data offset: 0x19800

known version: "AiR Setup Setup Data (5.2.0)"

Done.

I am not an experienced programmer, so what can I do to successfully extract this file or to help you adding this modification/flavour to your software? I have few files made by this modification. I've included both headers. I've also tried different versions (5, 2, 3, 0) etc. but then the error was thrown straight after "loading permissions". headers.zip executable.zip (pure EXE from 0xdee8d7)
