vCloud Automation Center 6.0 Installation fails with error code 1603 – Fix
So during my IAAS installation of vCloud Automation Center 6.0 (vCAC), I was getting the error during the installation saying:
VCAC Server Setup Installation Failed, ExitCode:1603
After digging and digging, I realized that .NET Framework 4.5.1 was installed. So as a hunch, I uninstalled .NET Framework 4.5.1 and re-installed it from the IIAS installation URL (https://vcac.domain.local:5480/installer/).
After re-installing, I was then successfully able to run the vCAC IAAS installer.
