How create a ".uproj" file with µVision ?

Hello every body,

I have just installed the µVision software.

When I create a new project, with my version   

I create a project .uprojx file by default and I can not use the "Xtal" option in the "Options for target":

How I can change my ".uprojx" by a ".uproj" or I can create a ".uproj" at the beginning of my project ?

Thanks for your help.
