Often, if you press “retry” to debug the application” you will be given a message “JIT must be enabled”.
Solution:
This is a relatively rare fault, and to date has always been caused by a corrupt font within the windows system of the computer running our program. Unfortunately there is no easy way around this. It means emptying the fonts out of Windows (usually C:\Windows\Fonts) and then placing them back in a few at a time until the issue reoccurs and the rogue font is found. Do not empty out any of the system fonts needed for your operating system.
