Hello,
Is there an option to disable checking the hash of the files? Or a way to create the hash and satisfy it?
To disable the hash file check you should make sure the
[Hash Files] button, from "Files and Folders" page (you can see it in the "Files and Folders" ribbon section), is not enabled.
Also, can you tell us if your setup package is digitally signed? This log entry may appear when the digital signature of the setup is not recognized by Windows Installer. So, please check if on the UAC prompt, spawned during installation by Windows Installer to request elevation, the digital signature/publisher of your setup is successfully recognized.
All the best,
Daniel
