I think there's a problem with Matlab. I'm unable to save a figure as png, using the basic command "saveas(gcf, 'test.png')". The figure does exist. The error is at the end of this message. Thoughts?

Can you save it by using the little disk icon on the figure's toolbar?

This seems to be serious: Several functions of the Windows KERNEL32 library are not found. Did it run before you have modified anything?
While the slashes are okay as file separator under Windows, I actually expect backslashes around the "bin" folder.

John's "Answer" moved here:
Update: I am able to save as jpg using the above command. However, as stated, png throws the error
Jan, yes, everything else seems to run fine.

Did you find a solution to that error? I get the exact same error message:
Missing symbol 'OpenProcess' in 'C:\Program
Files\MATLAB\R2017b/bin/win64\API-MS-Win-Core-Synch-L1-1-0.dll'
My program used to run until one hour ago and I did not change anything that I would know of...

Again, PNG does not work. Anyone have further thoughts?
