Tool throws exeption on 32bit windows: Unable to find an entry point named 'SignerSignEx3' in DLL 'mssign32'

[janez-praprotnik]

I've installed the tool through nuget and I've also tried with a source code compile for x86 and I get the sam error. I've tried to run it on 32 bit Windows 8 Pro and 32 bit Windows 7 Enterpriese SP1 with same result.

The same x86 compiled standalone exe works fine on Windows 10 Pro 64 bit.

Exception:

As noted in the Requirements of the README, AzureSignTool is required to run on Windows 10+, preferably Windows 11.

https://github.com/vcsjones/AzureSignTool?tab=readme-ov-file#requirements

Windows 10 or Windows Server 2016 is required. Some features require later versions of Windows.

I do agree that AzureSignTool gives a very poor error when run on Windows 8 or below. I will add an OS version check.

Ah, yes, sorry about that. I should've read all the documentation before posting and I probably wouldn't waste my time trying to get it to work on the build machine for VB6 app-s. I'll workaround it with a web api for signing..

Thank you
