Message

This project is already opened by another software or instance of HelpNDoc. Please close the project first.


Explanation

This means that this HelpNDoc projects can't be opened or saved because either:

  • Another instance of HelpNDoc has already opened this project without closing it
  • It is used by another software or anti-virus
  • It is marked as read-only or in a read-only folder
  • The Windows user doesn't have rights to read and/or write to that location


Solutions

  • Try rebooting your computer to make sure that no process is using that file anymore
  • Make sure that only one instance of HelpNDoc has this project file opened
  • Make sure that no other software has this project file opened
  • White-list that file or folder in your anti-virus software
  • Make sure that your Windows user has read / write access to that folder and project file
  • Try to move the project file to a local simpler path such as c:\doc\doc.hnd to see if that is working better
