Invoking: XDCtools permission is denied

Hi,

I am getting this error frequently when compiling a SYS/BIOS project using a Windows 8.1 pro machine. I have ran as Administrator, disabled firewall, antivirus not running. It complains about not having permission. This problem is not consistent. I clean the build, and re-build the project and it goes fine sometimes, sometimes I have to repeat the process many times until it decides I have permission it seems and it goes fine. Any help is appreciated.

Thanks
