I have added msiexec.exe to the process rule for Graph-Viz and msiexec.exe is part of the Microsoft installers process rule, but it is still returning "Deny Script File Program" and causing the application installation to fail. I have an AD group rule that elevates the Graph-Viz.msi installer and a process rule that elevates both Graph-Viz installer and Msiexec.exe. This has not given me issues on other applications which are MSI installers. I haven't had to add the Msiexec.exe to their process rules either. Any suggestions would be appreciated.
