XnView Software

Hello,
Each time I try to "save as" (with normal name and no special characters), it won't work.
In the past, XnView worked perfectly.
Now you cannot save a photo you modified.
What to do? I even tried "export". It's the same result. A box opens : File not found. Check the file name and try again.

I uninstalled it. I installed it again after one month. The program comes with the same problem.

Thanks in advance if you can explain me the problem.

Win10? in any output folder? do you have checked the rights?

Thanks for your reply.
I already solved the problem.
It's Windows 10 indeed, with it's antivirus: I had to go into settings and check permissions. XnView and a few programs were blocked. So I had to add it into the selection. No more problem.

Good day!
