Oddly, the problem was due to a networking issue on another computer on the LAN. 4D on my computer could detect that the other computer existed, but couldn't access any 4D resources on it.

When I try to launch any of these programs (4D Developer Standard), the 4D window opens with the Help menu visible, the spinning cursor appears, but the programs just hang. I have made no changes to my computer in the last 48 hours, and I don't believe that Windows has done a system update. All other programs on this computer launch with no problems. Here's what I have tried, with no success: * I trashed the AppData/4D folder * I uninstalled my virus protection software * I turned off Windows Firewall * I moved the Licenses folder to the desktop (just to see if I could launch any of the programs in Demo mode.) * I checked the Windows DEP setting and confirmed that it is set to apply only to Windows essential programs and services. * I rebooted the computer * I downloaded and installed a fresh version of one of the 4D programs - it won't launch. I have lots of RAM and hard drive space. Any other ideas anyone?
