Thank you for using Lovely Composer and question.
I'm not sure what the cause is, but I'd like to point out a few things to check. If that doesn't work, I might have to check the your log files to find out.
- At first, is the opened folder location the correct export folder? You can open that folder by clicking the folder icon on the export screen. Also, please make sure it matches the folder path displayed when the export is complete. (Generally C:/Users/UserName/Documents/LovelyComposer/export/ )
- Is there some kind of abnormality, such as the export folder not being found?
- There is a slight possibility that file export operations may be interfered with by file syncing software such as OneDrive, or antivirus software, so it may be a good idea to temporarily disable these and check.
- Most major operating systems today allow users to set permissions to prohibit reading and writing to specific files and folders. If writing is prohibited, the export will fail. (If you don't know what this setting is, it's unlikely to be a problem.)
You should be able to check this in the "Folder Properties" dialog.
Recently, I often hear about problems caused by OneDrive.
