Note for Windows Vista users:
Under Windows Vista (with User Account Control turned on) an application starts with only standard permissions, regardless of what level of authority the current user has. As a result, an installer run normally with an Admin account under Vista only has standard privileges and either is not able to write to certain critical areas of the registry/file system, or redirects the write requests to a per-user virtualized registry/file system.

Sparx Systems recommends that if you are installing on Windows Vista, always run the Enterprise Architect installer with Administrator privileges (recommended whether you have UAC turned on or not). To grant the application Administrator privileges, right-click on the downloaded installer icon and select the Run as administrator menu option.
