    lightroom 4 installation problem (windows 7)


      Hi, I'm having trouble installing Lightroom 4 on my Dell studio 15 laptop (64 bit-Windows 7, 4 GB RAM).  The installer seems to stop after the pop-up saying it is 'extracting Adobe_lightroom4_x64.msi'.  The pop-up disappears and nothing else happens.  I've tried restarting, uninstalling Lightroom 2, running ccleaner, re-downloading the installer, turning off Microsoft security essentials and the windows firewall, and starting up in safe mode (the latter gives a message saying it can't install in safe mode).  What else should I try?
