Cannot resolve error "This project is invalid or corrupt and cannot be opened. It may have been created in an earlier version of Quizmaker."

Hi Mark,

Sorry to hear about your project file. It looks like the file that you shared with us has become corrupted as it is now only 4 KB in size. 

You can try checking your computer's temp folder to see if you have any working backups of your project file. Here's how: 

1) Open this folder in Windows Explorer: %appdata%\Articulate\Quizmaker

2) Scan the contents of this folder for a file that starts with the name of your project. If you find one, copy it to your desktop. If you find more than one, copy the latest version to your desktop.

3) Change the file extension of the copy on your desktop from *.tmp to *.quiz.

4) Double-click the file to open it in Quizmaker.
