Interesting one today, installing horizon composer on a windows 2016 virtual machine. All the usual checks done for the ODBC settings etc, however constantly getting a rollback error message. After digging around in the logs i spotted error 1603., which after a quick check though the VMware knowledge base i found the following article Seems its a well know issue with thankfully a quick fix.

Power Down the virtual machine in question

Edit the virtual machine and disable Secure boot

Install Composer

Once installed shut down the virtual machine again

Re-enable secure boot.


So far its working for me.
