I am also facing a similar problem with InstallShield2020 (Installscript Project). I would like to be able to support SAC within InstallShield. During the installer execution, unsigned DLLs such as setup2Dll.dll and _isres_0x0409.dll are output to the temporary folder and those files are blocked by SAC. Microsoft offers a workaround using Package Inspector. Using that tool to capture the installer's behavior will output a .cat file. Sign it and copy it to %windir%\System32\catroot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE} before running the installer, and SAC will no longer block it. (The above two links are documents about WDAC, and SAC is realized with WDAC technology.) However, the need to place the files on the system BEFORE running the installer is a serious inconsistency, and the need to generate and sign a .cat file for each build is also very unproductive. ...
