ArcGIS 9.3 To Offer Full Support For Microsoft Windows Vista
ESRI has released a press release which talks about ArcGIS 9.3 and it’s support for Microsoft Windows Vista. The outcome brings integrated compatibility which increases stability. For those wondering if ArcGIS 9.3 will support Windows Vista, I think this answers your question. I am not sure yet whether it will support SP1 which has now been released. I would think it would but we would have to wait and see.
Integrated Compatibility Will Increase Stability
Redlands, California—ESRI’s upcoming ArcGIS 9.3 software release will fully support the Microsoft Windows Vista operating system across the ArcGIS family of products. The new support now makes ArcGIS fully compatible with Vista for increased reliability.Starting at the ArcGIS 9.2 Service Pack 4 release, ESRI added support for Vista in all the ArcGIS Desktop products: ArcInfo, ArcEditor, ArcView, ArcReader, ArcGIS Desktop extensions, ArcGIS Engine, and ArcInfo Workstation. ArcGIS 9.3 will add Vista support to ArcGIS Server (including ArcSDE and ArcIMS) and ArcGIS Image Server, helping to support the needs of developers building applications on top of these products.
ArcGIS 9.3 is expected to be available in the third quarter of 2008. Learn more about what is coming in ArcGIS 9.3 software at www.esri.com/whatscoming.
