I cannot get The Bing Maps base maps to work when I try to import them from ArcGIS online. I had 9.3 and found out that I had to have 9.3.1 to use the Bing Maps base maps. After fighting documented problems installing ArcGIS Desktop 9.3.1 on my Windows 7 machine, I now have the option when I "Add Data From ArcGIS Online" for the Bing Maps base maps. It shows the layer with 3 sublayers (aerial, hybrid, and road) in the data frame, but it doesn't display anything. If I load the DeLorme basemaps or any others, they all work fine.
I have Windows 7 with 9.3.1 installed. I have not yet installed Service Pack 1 or 2 because I get an error every time I try to install SP1. Error Message below if anyone cares to help with this issue as well:
"The upgrade patch can't be installed by the windowns installer service because the program to be upgraded may be missing or the upgrade patch may upgrade a different version of the program. Verify that the program to be upgraded existas on your computer and you have the correct patch"
