Dear all,

I've recently upgraded from Tiger to Leopard, and then to Snow Leopard.

The main problem that I have is that I can't install some applications, e.g. Netbeans, Parallels 5, etc. When it gets to the point in which the Install button is shown, I press it and nothing happens. I think it's here where the password should be asked, but as I say nothing happens.

Some other applications (e.g. Chrome) don't give problems, they can be installed and run.

I've verified and tried to repair permissions with Disk Utility, but everything seems fine.

I'd be grateful for any ideas that anyone might have and share.
