Error 1603 when installing Microsoft App-V 5.0 SP1 client

I wanted to do an unattended install of the Microsoft App-V 5.0 SP1 client.

I wanted to install using the MSI's instead of using the exe installer so I unpacked the MSI's from the installer as documented here.

The install failed however with MSI error 1603. I activated logging but that was not very helpful since it only logged "MainEngineThread is returning 1603".
