************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Expected behaviour
Shortcut has been placed successfully.

Enviroment (please complete the following information):

• Windows Version: Win10
• Version 0.9.5.25264

Additional context
The issue came up just recently. Have been using the software without any problems for a long time until now.

In the meantime can I suggest checking out @terrymacdonald's fork here:
https://github.com/terrymacdonald/DisplayMagician

There is a paragraph in the readme file about the state of this project and his fork that you can read for more information.

Thanks again for reaching me with this issue and more importantly with such a complete bug report.
