Go into the Administrator account
I assume you have 1 admin account and then 2 other accounts (yours and your lads)?
Therefore you have 3 accounts?
You have to use the Administrator account
What you have to do is go to start>all programmes
Now locate the programme, right click on the link to start the programme and then drag it to the desktop, now let go of the mouse and a box will appear, select "copy here"
Now restart your computer and your account and your lads should have the shortcut on the desktop
Or have i missed what you are saying?
