When trying to install I just get a blank page.
Any ideas what to do?
Bit more detail might help.
What OS are you using? Over wifi? When are you getting that blank screen, in other words what have you done to get to that point?
Note that Express has to be run as an administrator and the system requirements are listed here http://software.garmin.com/en-GB/express.html when you click on System requirements. Does your system meet them?
If you're saving the file to your hard drive right click the .exe file and select 'Run as Administrator'.
