Hi. I'm a relatively new Gramps user. I'm running
GrampsAIO64-4.2.5-1 on Windows 10.
I've downloaded the 3rd party add-on graphical report Descendants
Lines. But when I try to run the report I get the
error message "Report could not be created. Error while writing
to output stream".
Can anyone tell me where I look to try to see what the problem
The most likely as I see it is that you are trying to create the
report in a protected or a system folder. Gramps does not select
your My Documents folder when you save things, so you must take care
when using the file selector yourself.
