Well ---

registry shows

Code Select Expand

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0

Attached images of two schannel.dll files on the system, looks like one 64 bit one 32 bit
One matches your version.

Searched registry did not locate TLS 1.2 anywhere

Is it possible to switch yours to SSL 2.0?

Work in progress / USB microscope

This device didn't have any software with it's package, nor links for them.

Windows 7 DirectX can show this device, but i can't find an old  WebCAM code right now.

That device works in Windows 1x, but those apps aren't so good.

That device isn't allowed use by children under 8 years.

Perhaps more to come later.

It works perfectly in Win 7 PRO.  Pro versions contain more intrinsic features than
other versions.  I still get security updates for Win 7 PRO too.

What version is that a schannel.dll and is in register TLS 1.3 ?

I have dll 6.1.7601.24545 2020-01-03, that support TLS 1.2

Thanks for the link Timo!

Attached is the 64-bit version.

I can test on Win 7 PRO, but I need to know a location and file to try to download ....

You would probably have to install some hotfixes on Windows 7 and do some registry tweakings. Better is WinHTTP.

ChatGPT suggests :

You must install these (even if Win7 is "fully patched"):

Update   Purpose
KB3140245   Adds TLS 1.1 / 1.2 support to WinINet
KB3055973   SChannel improvements

Hi Timo,

Probably, I need to rewrite the application employing WinInet functions.
