While attempting to install ArcGIS Desktop, the following error(s) occur:
"Error 1904: failed to register C:\Program Files\ArcGIS\Bin\ESDA.dll (or GARenderer.dll, GAEngineLib.dll, GAmethods.dll or GAMethodsUI.dll). HRESULT -1073741795. Contact your support personnel."
These errors are caused by installing ArcGIS Desktop on an unsupported processor. SSE2 support is required for ArcGIS Desktop and is not provided by older Pentium 3 or AMD XP processors.
These files are related to the Geostatistical Analyst extension. If this extension is not going to be used, click Ignore to these errors and allow the installation to complete. The rest of ArcGIS Desktop should function normally.
If the Geostatistical Analyst extension is going to be used, install ArcGIS Desktop on a different computer with a supported processor.
