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).

A new tool came out in Dynamics AX 2012 R2 CU7 which is AxBuild. This tool really help us to make the compiler run faster. Here is the screenshot of the parallel compilation using AxBuild.exe.

I have tested my self this tools run in virtual machine and it takes 1 hour 5 mins to do the full compilation.

Dynamics AX 2012 RTM upgrade form freeze

Hi, there is one time I need to do single patch for Microsoft Dynamics AX 2012 (not R2). Once I applied the patch then restart the AOS, open up the AX application then the upgrade form is show up but you can not choose anything, just like a freeze form. I wonder this is bugs from Microsoft or something else.

After I tried many times until I found that you can choose the options from the development environment use parameter -development
Here is the official link from microsoft how to open Development environment.
