Error message: E_IO_cannot_open

This error is caused by Adobe Digital Editions (ADE) needing to create a temporary folder in your Windows TEMP folder in order to download the ebook. But for some reason the permissions on your TEMP folder have been changed so it is read only. To resolve the issue please follow these steps:

  • Navigate to "C:\Users\[[Name of your user account for that computer]]"
  • Right click on the temp folder and select "Properties"
  • Near the bottom there is a checkbox titled "Read-only (Only applies to files in folder)". Make sure this checkbox is unchecked
  • Then click "OK"

Even if this fixes the issue it is possible that whatever changed the temp folder to read only could change the settings again, so if it reoccurs you may need to follow the above steps again to resolve the issue.

If you are still receiving the error please contact our support team. Please quote the error message when doing so.
