I have the following strange exception on my application,
System.IO.FileNotFoundException: Could not find file 'C:\Users\MYUSER\.accessibility.properties'. File name: 'C:\Users\MYUSER\.accessibility.properties' at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
where I can find this file accessibility.properties
The system cannot find the file on that location.
Have you searched at C:\Users if there is the file "MYUSER.accessibility.properties"
My guess is you need to search at C:\Users\MYUSER\accessibility.properties (notice the \ after MYUSER).
