The different error code is probably a different issue. To help you further, perhaps you could post the log from your install process? Carlos provided a sample commandline that will generate installer logs(just be sure to replace UnrealEngineInstaller.msi with the full path and name of your installer. You may need to use quotes if there is a space in the path). If you are unable to generate the log let me know what folder your .msi is in and I’ll provide you with a full command you can run.
msiexec /i C:\UnrealEngineInstaller.msi /L*V UnrealEngineInstallerLog.txt
Sure thing. I will try to get back to you when I get home from work, but I may not be able to get to this until next week as I’m heading out of town.
The few lines around “MSI (s) (24:7C) [13:48:04:752]:” in your log file seem to imply that Windows Installer is not able to access the source msi file for some reason (Ex. C:\Users\Downloads\UnrealEngineinstaller.msi). Is that folder or drive encrypted? If so, try moving the installer to a folder that is not encrypted before running it.
Wow, so simple. All I did was move the file from the downloads folder to the desktop. It worked. Thank you for your help and sorry for such a simple solution.
A user with the same issue provided logs which confirmed one of my suspicions. Perhaps you could try the steps outlined in this thread:
