Are you aware that now we can install application updates (or a subset of them) using the advanced installation option in the CU7 installer? I wanted to demonstrate how you can do it. I hope it can help those who want to update specific bits without upgrading the whole application.
1. Download CU7 installation package and run the axupdate.exe and install the components (it's a prerequisite to use the Advanced installation option)
2. Reinitialize the model store (read mode details)
3. Restart the axupdate.exe select Database and then Advanced installation
Now you can select the modules to update or specific hotfixes.
For any hotfix, the details pane displays the title of the hotfix, the model and any updates that are included.
