Unable to create process: Performing Streamed Install

Hi all. 

Apologies - newbie alert (new to Delphi, not programming)

I have installed Rad Studio10.3 and I am attempting to get some Android development working.

The installed sdk is 25.2

I have created a virtual machine and when I activate it and hit the run button I get the following message: 

Unable to create process: Performing Streamed Install

Anyone know what that means? Any other info I need to add to this to help?

Thanks, Jeff.
