STVD displays message on building the demo code from the tool itself. I am a newbie and starting with the mcu. Any ideas what and how to resolve it?

[Ssank.1]

----------- Project ew - ST Assembler Linker - Configuration Debug -------------

Assembling mapping.asm...

asm -sym -li=Debug\mapping.lsr mapping.asm -I="C:\Program Files (x86)\STMicroelectronics\st_toolset\asm\include" -obj=Debug\mapping.obj

   No errors on assembly of 'c:\program files (x86)\stmicroelectronics\st_toolset\stvd\mapping.asm'

Running ST linker

 The command: "lyn Debug\mapping.obj+Debug\main.obj, Debug\ew.cod, " " " has failed, the returned value is: 2

exit code=2.

Resolved it by running STVD by right clicking "run as administrator". The file compiled & build without error. The message accesss denied for saving also went away.
