Today , I encountered the below error when trying to run my windows phone project after upgrading my system from Windows 8 to Windows 8.1
The Error Message was
“The Windows Phone Emulator wasn’t able to ensure the virtual machine was running:
Something happened while starting a virtual machine:”Emulator WVGA.<Name>” could not initialize(Virtual machine ID <ID>)
Not enough memory in the system to start the virtual machine emulator WVGA.<Name> with ram size 1024 megabytes”.
Looks like there were too many applications running on in my system which included 3 simultaneous instances of Visual Studio 2012, Multiple Browsers etc. and these applications were taking up most of the memory.
The issue was resolved by closing the unwanted applications which made sure there was enough memory available for the emulator.
