I ran as administrator and the IDE loaded up.
I ran a sketch and it compiled it.

Thanks Louis for all your help.

The program did work on this system several months ago but all sorts of window updates and such have occurred since then. 
Do I need to be administrator to run this program?
Do I need to load the latest java updates?
Is there another way of invoking the executable? Batch?

Thanks again

I did as you suggested and got an output file which I have attached.
Its quite big at 31K bytes.

Hope this helps.

Thanks again.

I tried to enter the first command as you suggested but I could not get an IDE.
I tried the second command and a window came up with data but it closed as soon as it opened.
I could not capture the contents.
I am using "Run" from the accessories folder and it will not take the whole command, it leaves out the "processing.app.Base>output.txt" portion.
I tried using the command prompt and typing in the whole second command but nothing happened at all.
Where would I expect to find the output.txt file?
Is there a way of capturing the window that pops up?

I am new at this.
Thanks for your help.

I am having the same problem.

I deleted the preferences.txt file but it had no effect.

I ran the launch4j with the debug turned on, following is the log file contents.

Does this give you any clues?
