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

[Kutty, Rejeesh]

Hi,

I can't  launch setup-x86_64.exe, but setup-x86 runs fine.

PC Info:

Windows 10, 20H2, OS build: 19042.1348
64-bit operating system, x64-based processor
Windows Feature Experience Pack 120.2212.3920.0

I tried to run from a command prompt, same behavior.
I tried various flags, -B, -a, -t, -V, same behavior.

I tried to debug using the WinDBG tool, here is the output:
Apologies in advance, if the following is irrelevant.

Hi Kutty,

It works fine on my W10 21H1

May be a corrupted download ?
Can you download it again ?


You can also try the last setup snapshots:

[Kutty, Rejeesh]

Google says it is part of the Beyond Trust stuff, for security?
I couldn't find anything that tells me how to disable it.
Is this DLL the problem?

Could be.  Is Beyond Trust something that you have control over?  Can you 
uninstall it, or temporarily suspend it, or tell it to exclude certain directories?

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

[Kutty, Rejeesh]

I tried two things (though may not make sense).

Renamed that DLL -- same behavior, and same  access violation in WinDbg.
Killed all Beyond Trust Services/Tasks -- same behavior.

Does WinDBG still show the DLL loaded?

[Kutty, Rejeesh]

No it didn't, but it reported access violation after RPCRT4.dll.
(This is the RPC API, as per google).

You will probably need to restart Windows after any changes in order to 
unload or reload DLLs and associated data.

Many of these apps have difficulty handling dynamic modification, 
cleanly removing themselves from the call or message chains they insert 
themselves into, transparently passing along arbitrary calls, data, 
events, or messages, especially when application code is multithreaded 
and reentrant using mutexes and waits.

Beyond Trust is on the Cygwin Big List of Dodgy Apps: poorly written 
(often so-called "anti-malware", "anti-virus", or "security") software 
that monitors, logs, blocks, and/or interferes with normal operation of 
many applications, with effects sometimes indistinguishable from 
malware, and known to prevent Cygwin working properly; see:

	https://cygwin.com/faq/faq.html#faq.using.bloda

Beyond Trust has caused problems because its certs became outdated 
unless you kept the product and its certs updated. Try updating the 
product and check its certs are up to date in the cert store.
If that fails you may need to raise a case with the product vendor 
regarding Cygwin 64; especially useful to mention:

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

[Kutty, Rejeesh]

I uninstalled Beyond Trust with our IT help, rebooted, same behavior.

I then came upon another thread that talks about the compression.
I didn't build it, I just decompressed it and now setup-64bit works fine.
For some reason, 32bit doesn't have any of this problem.

If it is not too much of trouble, I would request that you provide an uncompressed version too.
The file size is not that bad, It came to be about 5MB only.

Perhaps,  suggest in the installation instructions to try in case it doesn't launch?

Thanks for all your help.

What was the URL of the thread about compression?
Which file did you download about 5MB, from which URL, how did you 
download and decompress it: using which tools, commands, options, and 
what were the before and after sizes?
There appear to be no Cygwin setup files about 5MB:

he means 5MB after decompressing the 1.3Mb setup-x86_64.exe

If I remember right upx is used for setup compression

If you have that problem, you have an app in the BLODA.
Are you still running BeyondTrust or another AV?
You need to get Cygwin setup exes using upx bypassed or whitelisted by 
your support or the vendor.

Why would anyone want or need to do that manually: that implies a badly 
written app in the BLODA interfering with decompression, and that hasn't 
had any mentions as a problem for a couple of years!

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

[Kutty, Rejeesh]

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

c:\TEMP>

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 ?
