The installer doesn't support multiple instances. Is there any workaround for this? We have multiple AOS with different versions and the client is installed on the same machine. Every time we start the client we get "Internal version mismatch" warning in the event log.
When you install multiple versions of AX on one machine, you have to know that some values are stored in the windows registry. There can be only one default version.
You can handle this by creating shortcuts opening ax32.exe (from a specific directory) and the appropriate configuration file in one link.
Another possibility is to use multiple machines per version, if possible of course.
If you plan to run one major version and multiple SP or CU versions you will definately have a challenge...

Do not mix versions of the kernel of the client and the service itself. If your service is using a kernel with as an example version 6.0.1108.2423 (AX2012 RTM CU4), then you should use a client with the same version. Any other scenario is not supported by Microsoft.
Do not mix AX2012 and AX2012 R2 on the same machine. They use a different version of the binaries (184.108.40.206 vs 220.127.116.11).
Kernel versions will increase the buildnumber (last digit) when installing updated CU or hotfixes. These will by design be backward compatible with the application version, as long as the two first version numbers match (6.0.1108.2423 - CU4 - kernel supports a 6.0.947.61 - CU1 - application version).
More in-depth around Feature Pack versioning:
If your AOSes are on the 6.0 version, just keep the kernel at the highest version for both service and client. The kernel should be backward compatible with the application code in your various AOTs.

We have AX2012 R2 (18.104.22.168) and AX2012 R2 CU1 (6.2.1000.156) on the same machine. When I connect to AOS with AX 2012 R2, "Internal version mismatch" appears in the event log.
If I had the time to find the reference, I would, but I can assure you, RTM and R2 is not supported on the same machine. Avoid it or live with the instability and errors.
