Hello,
I have a similar problem, but contrary to Eamon, all other components of ArcGIS open and function properly(ArcGlobe, ArcScene, Arc Catalog) except for ArcMap, wich initializes but never opens. I am running vista Home Premium 32-bit SP2, Intel Core 2 Duo 2.2GHz, Nvidia Geforce 8400M GS, 4gb ram and 250gb hard drive. ArcGIs 9.2 worked fine on this computer and was uninstalled before installation could begin. Do I need to follow all the steps as described in the previous pos, or is there an easier way.
