Dynamics AX 2012 R2 software upgrade checklist can't expand on windows server 2012

After we upgrade the AX 2012 R2 into a new CU we need to do the sofware checklist update inside AX as a routine after installing the hotfix or CU. If we open the client and run the software checklist update on Windows Server 2012, the check list item can't expand when we click the expand (+) and if the check list item can't expand then we can't go through the check list process.

I'm not sure what is the missing part here but looks like Windows server 2012 not certified yet for Dynamics AX 2012 R2 client.
To solve this issue we need to run the software update checklist in AX client under supported client OS (I have tested in Windows server 2008 R2 and Windows 7).

Dynamics AX 2012 R2 client crash when doing full compilation on windows server 2012

I don't know what cause this client crash when we do the full compilation of Dynamics AX 2012 R2 on windows server 2012. I just found only few times I didn't get the AX client crash but 90% it will crash.
Some forum in Microsoft said that Windows Server 2012 only certified for the AOS but not for the client.
I have tried do the full compilation for the Dynamics AX 2012 R2 CU1 and CU6; both have the same client crash.

One of the solution that I found is to run the full compilation using Dynamics AX client running on Windows server 2008 (with or without R2) or Windows 7.
