Qest Won't Launch Without Saving a File
If when trying to access Qest through Remote Desktop Connections, you get a popup (below) asking you to save a file instead of launching the program as normal, you need to clear out your downloads folder.

You will simply need to open the Downloads folder on your computer and delete any files that are of the Remote Desktop Connection type as shown in the picture below.

Chrome will only allow files with the same name to be downloaded 100 times, so you will be required to clear these out after opening Qest or Timberline 100 times.
