Well, I can't help you further -
other than sending your message to the list so others might add
their suggestions
Hi,
When you say "unable to open"...the program crashes when you click on it? Or you can't find the program? Or something else?
A step by step run through might help us to diagnose the problem
Windows/Linux/Mac? If you could advise this then someone should be able to advise how to run from the command line which may throw up more information.
Cheers
I have downloaded and installed, but unable to open
What specifically did you download?
The name of the specific file?
