Hello , i copied project file to another computer system but it doesn’t work with error massage (Unable to open (file path) zip.open():%d)
Then the file didn’t copy correctly or is corrupted. Your best bet is to upload the file here ((either the .fzz file or the .fzpz file if it is a part, upload is the 7th icon from the left in the reply menu) and one of us will try it and see if it works for us.
