UNC paths not working

I’ve noticed that .exe files wont work from a unc path, unless you use a mapped drive letter…

example#1 open your network folder with the drive letter (works)
X:\your\files\are\here\unitygame.exe

example#2 open your network folder with the server path (doesnt work)
\yourserver\your\files\are\here\unitygame.exe

Is this a limitation or is there a workaround?

Thanks

There was some info here on the last post,
