If you receive the message "The DLL being called encountered a problem" when downloading the Bookshelf desktop application it is usually because of a corrupt OS install or missing Windows updates. This should be resolved by installing all recommended Windows updates and rebooting the computer before attempting the install again.
If the error persists, you will need to run a scan on your computer to check for errors.
- Go to Start menu > All Programs > Accessories > right-click on Command Prompt and select Run as Administrator.
- Now type this command in the command prompt: sfc /scannow
If this scan repairs errors, please then reboot Windows and try and run Bookshelf again
