Thanks. Make and model are shown below. It's a desktop, and there is no separate video card. Google Earth always worked perfectly until I installed AVG2013 and AVG Tuneup. I have removed AVG and installed Microsoft Security Essentials but it has made no difference. It still says "DirectX mode not supported. NOTE: if the login Status" is blocking access to this window then do the following: click on the login window, press ALT-F4, then read the message below." The details are the same as Jenny72 post: "check32-bit,etc." but alll to no avail. Any login window I encounter does nothing when I press ALT-F4. Is this a login stauts block of some kind? Greatly appreciate any further help. Thanks again.
