| Problem | Likely Cause | Solution | |---------|--------------|----------| | "ArcGIS Desktop is not installed" error during SDK setup | Mismatched version or missing registry keys | Install exactly 10.8 ArcGIS Desktop (not 10.7 or 10.9).

Try Edge or Chrome incognito mode. | | Visual Studio templates missing after install | Visual Studio was open during installation | Close VS, rerun the SDK installer and choose "Modify" → ensure Visual Studio integration is selected. Then, run devenv /installvstemplates from Developer Command Prompt. | | "Cannot register COM class" runtime error | ArcGIS license not initialized or missing license file | Call ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.Desktop) before any ArcObjects calls. Also ensure your ArcGIS Administrator has a valid license. | | No "ArcObjects SDK" in My Esri search results | Account lacks entitlement | Contact your organization’s Esri license administrator to assign the "ArcGIS Desktop Developer Kit" product. |
