Png file as background in PBI Desktop resolve in Error "Part URI is not valid..."

[Anonymous]

When I add a background (png) to my PBI report in PBI Desktop I am not able to save the file.

I get the error "Part URI is not valid per rules refined in the Open Packaging Convention specification".

After I close the error window, I get the following error message when I try saving the pbix-file: "Unable to Save Document -  'C:....... .pbix' is not a valid file path"

How to get around this error?

The png file is created from ppt and includes a logo and two lines.

I am using the neweste PBI version (released in November 2016).

Good to hear that it solved.

I figured out the png-file format in some way was not supported at the clients systems.

Png-files had some restricted use. I tried to create another png file at my locale computer. This file worked.

The png-file was "corruped" so to say.

Something not quite right.I never had a problem putting png images in the PBI Desktop. Could you please 

share your sample file with png image if possible.
