Allow more than 1 instance in Excel 2016
Can you please bring back the ability to open more than 1 instance of Excel? Currently when I have a macro running, I am unable to utilize Excel because of this new setup. In the older versions of Excel, it was nice to be able to choose how many instances you wanted to open.
This is already supported. To start a new Excel instance, press Windows+R (Run), then type “Excel /x” without quotes.
You’ll get a new process that will be isolated from other Excel instances.

there is a registry key you can put into the HKCU\Software\Microsoft\Office\16.0\Excel\Options
DisableMergeInstance as a DWORD and set to 1.
Then every instance will launch seperately. If you want something in the same instance, then use File->Open from that instance
This is not fully supported.
When opening from explorer (double-clicking) on an Excel document, there is no option for running in a separate instance.
