Setup not working

[-- Attachment #1: Type: text/plain, Size: 242 bytes --]

I am running a Windows 8.1 Pro machine. Once I run the setup wizard,
nothing happes. The installation is supposed to be successful, but I cant
find Cygwin on my machine.

Has somebode also experienced this problem? If yes, how was it solved?

There is a set of messages from last year or the year before talking about how the Cygwin setup program is compressed with "upx." When I had this issue, I had to download UPX on a Linuux host, copy the setup program to that host, and use upx to uncompress the executable. Why? Because my corporate-mandates security software blocked the UPX extractor from executing. If you have a Windows host where you can shut down the security software, that could work too.

I understand the desirability of compressing everything that travels
over the 'Net, but the days of there being any reason to keep an
executable compressed in order to save storage space have long passed
for the vast majority of users.

Therefore I suggest that a version of 'setup' be made available that
is compressed using one of the standard versions of 'ZIP' that Windows
File Explorer recognizes. People who have any issues getting setup to
run can download the ZIP version and use Windows File Explorer to
extract the uncompressed executable.

I suspect that even using a less than optimum ZIP process will still
be size-competitive with the self-extracting version because of not
having to include the overhead of the self-extractor.

I had a little too much faith in ZIP, but 7zip is a winner. I
downloaded UPX and used to extract the latest version of setup. Here
are the file sizes following re-compression with 7-zip for the
original setup and the re-compressed .7z and .zip outputs:

1,381,395 setup-x86_64.exe - 100%
1,319,604 setup-x86_64.7z -  96%
1,795,036 setup-x86_64.zip - 130%
