Orchestrator Install Fails at 75% : Failed to execute MSI package? 2020.4.2

I am standing up Orchestrator for the first time in our environment. I get to 75% completion of the install and then it fails.

The logs are not very helpful to me, maybe someone else can make sense of them?

There was an issue with Database permissions that I overlooked and the installation wasn’t able to create the database.

I was only able to locate this problem by running the platform installer, finding the temp folder that the orchestrator msi was placed in during install, copy the msi out, cancel the platform install, then run the msi installer.

At the end of the msi installer it produced the “failed to create BD” error and rolled back the install.

With this information I was able to identify the problem.

I searched the logs for the platform installer and it does not mention any issues with the DB and its creation.

I am unsure why that error does not appear in the install logs for the platform installer but I think it is a large oversight for them to be excluded.
