New to Java

Hi,

I wonder of you can help me please, I'm new here and looking for an answer to a problem with my Java files.

Perhaps I should start a new thread for the new question? Please advise me...

'Problem' is:

When I try to open the 'Java' icon on the 'controll panel' page, it says 'Application not found' !? :(

I have tried re-installing Java but it still says 'Application not found'.
(There is a plain box on the control panel, where the Java sign should be, but nothing else.)

Also, when I try to use the BT speed tester, it tells me that 'Java is not installed/enabled on your P.C.'

I am pretty sure I have ticked the right boxes on 'internet options', (under 'Tools',) but this doesn't work and even when I restart it says: 'restart required'.
