Error 1603: A fatal error occurred during installation.
Windows Installer is attempting to install an app that is already installed on your PC.
The folder that you are trying to install the Windows Installer package to is encrypted.
The drive that contains the folder that you are trying to install the Windows Installer package to is accessed as a substitute drive.
The SYSTEM account does not have Full Control permissions on the folder that you are trying to install the Windows Installer package to. You notice the error message because the Windows Installer service uses the SYSTEM account to install software.
Please check ‘Tools > Settings > Remote Execution Context’ in BatchPatch. What is your Deployment context set to currently? Is ‘Interactive’ checked? Please try unchecking it and see what happens. If no luck, please try the following different combinations and let me know if any of them is successful:
1. SYSTEM
2. SYSTEM + Interactive
3. Elevated token
4. Elevated token + Interactive
It’s good/fine to leave it that way. Actually ‘SYSTEM’ without interactive, is the default setting in the most recent version of BP for ‘Deployment’ because as of today, we think this is probably the most compatible option for deployments, in general. However, it’s possible that you could encounter a deployment in the future which requires ‘Elevated token’ instead.
