I created a winForms app (c#), and it works great from the vs and from the appName/bin/debug/appName.exe, the problem occours when I copy the .exe file to another folder - it doesn't open. When I published it and try to install - it showed the messege "cannot find the appName.exe.config.deploy file". But I checked the folder and that file really exists there! Does anyone have an idea what can it be and how can I fix it? Thank you all!
