Signtool file in use error when creating exe in version 18.7

Thu Oct 14, 2021 9:17 pm

I am getting an error in the final sign when building. The CAB & MSI sign just fine, but then when it signs the .EXE (last step so the installer exe) it says the file is being used by another process. But it is not me. Full error message below, only changed my file paths.

Am updated to current version 18.7 (0A7FDEAD) Windows

- Thank you.

Hello,

I am not sure why this happens.

I believe that this most probably is not related to Advanced Installer, as we use the SignTool.exe tool (from Microsoft and which comes installed with the Windows SDK).

Can you please verify if an antivirus/anti-malware running in the background may be restricting access to the file?

Also, check if you have an application open which is listing the folder where the files to be included in the setup are located. If the file is being previewed, then this kind of error also may occur.

As I can see, other people with similar issue said that excluding the build folder from Windows Defender helped them: SignTool error: installer EXE is being used by another process

Please let me know if that helped!

Best regards,
Liviu
