Code Sign Problem

[hafedh-trimeche]

Hello,
Please note that when debug information is embedded into executable file, it won't be signed using SignTool from Microsoft.

Using this command:
signtool.exe sign /f "D:\Developer\Tools\SSL\Certificates\Strong Data\Code_Signing.pfx" /fd SHA256 "D:\Applications-Folder\RMSServer\RMSServer.exe"

an error is generated:

Done Adding Additional Store
SignTool Error: SignedCode::Sign returned error: 0x800700C1
        For more information, please see https://aka.ms/badexeformat
SignTool Error: An error occurred while attempting to sign: D:\Applications-Folder\RMSServer\RMSServer.exe

Number of errors: 1

Here it works ok in PyScripter. (jdbg info into executatble) and the signtool works ok.

perhaps there is a sensitivity to the large size of the jdbg

[pyscripter]

Does the executable with jdbg included work as expected?
Does signing work, if you do not include the jdbg into the executable?

[hafedh-trimeche]

Yes the executable works as expected when jdbg is included.
Indeed, the signing works when jdbg not included.

When do you sign the exe? Automatically in a postbuild event? Or manually a few seconds after inserting the jdbg info?
Also, that error code may come from using a x64 signtool on x86 exe files, or even when the exe file is already signed.
