Dear all,

I am having problems with r.viewshed.cva addon. I've already re-installed
it several times, but the error continues.
Note that the routine is constrained to points in the current geographic
Traceback (most recent call last):

Hope anyone could help. I am using GRASS 7.0.3 in a Windows 10 laptop. I
tried to use it 7.0.4 version, and the error is the same as before, but

WARNING: Illegal filename <vshed_1
>. Character <
> not allowed.

Thanks for the attention,
