Installing an additional AOS on an AX 2012 R3 CU8 environment

Please note this is only for environments that were not installed with CU8 slipstreamed, but rather had Ax 2012 R3 RTM installed, and then upgraded to CU8 or had CU8 installed afterward.

This is the event log error you will see:

Issue:
Basically the AOS will not start due to the kernel version difference between the AOS and the database. Nothing else will install due to the AOS not being able to start. Upgrading the AOS to CU8 will allow it to start, but then nothing you install later (client, BC) will be able to connect to the AOS, since they are RTM and the AOS is now CU8.

Solution:
Slipstream CU8 and install the AOS again.
