Using our own version of SignTool.exe with InstallShield 2021 R2.
We have to use a USB signing token in conjunction with our SHA-256 certificate. To make that work with InstallShield 2012, we replaced the signtool.exe in the \system folder with our own 'shim' which changes the parameters and then calls the real signtool.exe
However having upgraded to InstallShield 2021 R2, we see from our installation and from the user manual that SignTool.exe is no longer installed in the \system folder. So our question is - which signtool.exe is used and how is it located on our system?
