setup-x86_64.exe does not start in win10 20H2

MD5SUM from bash shell: (seems to match)

[/cygdrive/c/Users/rkutty/Downloads]> md5sum setup-*x86_64.exe
82f0a6cf3a2b228acf0b2009dc6f6d42 *setup-2.909.x86_64.exe
02bf88888c1db4b4e5ead39c1812bd13 *setup-2.910-3-g217aad.x86_64.exe
be948258a63ff971c6f21ebc2a8af43e *setup-2.910.x86_64.exe
82f0a6cf3a2b228acf0b2009dc6f6d42 *setup-x86_64.exe

Trying in a different folder on command prompt:

c:\TEMP>setup-2.910.x86_64.exe -V

But If I run 32bit:

c:\TEMP>setup-x86.exe -V

c:\TEMP>Cygwin setup 2.909

can you check the files ?

$ md5sum setup-*x86_64.exe
be948258a63ff971c6f21ebc2a8af43e *setup-2.910.x86_64.exe
02bf88888c1db4b4e5ead39c1812bd13 *setup-2.910-3-g217aad.x86_64.exe
82f0a6cf3a2b228acf0b2009dc6f6d42 *setup-x86_64.exe

additional, as I see

CommandLine: C:\Users\rkutty\Downloads\setup-x86_64.exe

Can you also try to run it in a different directory like C:\TEMP ?
