I'm not sure where to post this but I'm having problems with the installation manager in Solidworks. When I try to upgrade to SW2011 SP1, Solidworks Installation Manager gets to the point where I can choose the upgrade, but for some reason the buttons, Cancel, Help, and Next, will not work if I click on them. I can click the "X" up at the top right corner to close the dialog box, which it then asks if I really want to close and those buttons work, but the buttons I need to work do not. I'd call my reseller support, but they're not open on the weekend. Anyone have any ideas, websites that would help, anything???
