I too would be very interested in hearing about any version of Wine where this
worked, as I have found none myself.

I have done some research on this and here is what I have come up with so far.
As I said in the original report, the setup seems to be protected with what
PEiD identified as "k.kryptor 5", but I have no idea if this is accurate. In
any case, it works like this. Setup.exe is not the real executable, Setup.cab
is. You can try this by letting wine execute the cab directly, it will appear
to work but installation will fail and abort as the code is missing several
pieces. Setup.exe is a obfuscated/self-modifying executable and "creates"
itself first using exception handlers, then chain-loads setup.cab and restores
the missing code in the "real" file by writing to process memory, finally the
real setup is executed.

I'm attaching another logfile, please let me know if there is more I can do to
help solve this.
