Can't install backup

Hi

I have Sandisk ultrabackup and was trying to install the backup application.

A window opens to accept licence agreement but there is no box to tick and next button is grayed out.

I have win7 64, tried compatibility mode for win xp.- didn’t work

Also a small window pops up that lastest software update is available, but downloading stops at different points and the backup program not responding

any solutions to this?

thanks
